Biomedical engineering: career tips & education information

Engineering has a lot of subfields that offer students the possibility to broaden their potential career paths. One of these subfields is represented by biomedical engineering, which combines more than just one discipline. If traditional engineering is focused on mathematics and other applied sciences, biomedical engineering also includes fields such as biology and chemistry. Biomedical engineering, shortened BME, is a multidisciplinary field that combines various fields, namely medicine (diagnosis, monitoring, therapy) and engineering (solving skills). BME has other subfields as well, depending on the branch that is selected by the engineer. For instance, one can specialize in biomedical optics, tissue or genetic engineering, pharmaceutical engineering or even neural engineering, all being related by the aforementioned solving skills. Biomechanics combines the mechanics method which is studied in traditional engineering with the functioning of the human body from a mechanical point of view, thus combining basic biology with the concepts in engineering. Here are some other details related to this field:

What duties biomedical engineers have?

Biomedical engineers usually engage in a very specific type of activities that differ from one branch of biomedical engineering to another. There are a few tasks that are common for multiple branches. The basic biomedical engineer should be able to come up with medical equipment prototypes. For instance, biomedical engineers are the ones behind creating artificial organs that can replace actual human body parts. Combining the mechanics of engineering with the science of medicine has such medical equipment as a result. Biomedical engineers also need to provide technical support for the equipment they create in the field of medicine, especially considering that the health of people depends on the use of it. Biomedical engineers hold a great responsibility because they need to assess the state of the biomedical tools. A safe environment of using these tools is evaluated solely by biomedical engineers. Other duties involve training people who work in the medical field to use the equipment that biomedical engineers create. The personnel has to use the equipment correctly in order to obtain the safest results. Biological engineers can also research topics of interest in fields such as chemistry, biological systems of animals or other sciences in order to come up with new, innovative approaches. Based on the research they obtain, biomedical engineers can recommend various procedures that may revolutionize the medical world. The basic duty of a biomedical engineer is to design new devices for the healthcare industry, and other tasks result from this one. Biomedical engineers can also opt for specializing in one single field after obtaining their diploma. A few of these specializations include instrumentation, materials, mechanics, clinical and rehabilitation, all in a relationship with the biological field. Bioinstrumentation mostly refers to developing the necessary tools in diagnosing/treating certain medical conditions. Biomaterials mostly refer to studying implantation devices. Biomechanics combines multiple disciplines among which studying chemistry, physiology, thermodynamics to come up with solutions for a wide range of medical challenges and issues.

Relevant skills for biomedical engineers

When it comes to who is suitable for becoming a biomedical engineer, there are a few skills that one must possess in this sense. First of all, the person must have analytical thinking. All engineers need to analyze information in depth and come up with unique solutions for uncommon problems. The second set of skills that are required to perform well at this job is related to communication and speaking. Without proper communication skills, biomedical engineers wouldn’t be able to understand the needs of the patients or the doctors that they work with. Moreover, biomedical engineers usually work in teams, which means they need to handle teamwork projects efficiently, or even lead them. Being a biomedical engineer also requires creativity and imagination. Even though creativity is sometimes placed oppositely to analytical thinking, engineers require it in order to come up with innovative solutions and devices. The advancements in healthcare wouldn’t be possible without the launch of new devices and technologies, which strictly depend on the creativity of biomedical engineers. As implied by engineering, math, chemistry, and physics are also part of the skillset that biomedical engineers must possess. Dealing with problems everyday implies strong problem-solving skills.

Education requirements

As for the level of education needed to perform as a biomedical engineer, a few factors must be considered. First of all, biomedical engineers may need to follow multiple areas of study, depending on the selected specialization. A biomedical engineer working in research only needs one degree. A biomedical engineer that works in a topical area may need degrees in more than one simple field. Some biomedical engineers follow studies in managerial sciences as well. The education level solely depends on the branch selected for performing further. In most cases, the basic engineer MBA will only ensure a place in basic research jobs. Depending on the type of studies that were finished by the biomedical engineer, the salaries may differ. An engineer that has a multiple degrees may generate an average annual wage of $100 000, while a biomedical engineer that only works in healthcare may generate one of $50 000. Education is a determining criterion of the salary and all fields involve full working hours and interacting with patients, managers, and doctors on a daily basis.

Job opportunities

As for job opportunities, some countries are in need of biomedical engineer positions while others are saturated in this sense. The number of job opportunities differs from one year to another, but several studies determined that the jobs in the field of biomedical engineering will be increased with almost 10 percent until 2025. Because of this reason, the employment in this field will suffer a beneficial growth that is going to allow more people to have a career in this field. The current technological advancements also sustain the demand of biomedical engineers, as they are the only ones who can create innovative devices that could completely revolutionize the medical field. All people who are thinking about following a career in this field should take advantage of this growth and the considerable salaries offered.

PBN in 2019: New Best Practices to Employ

It’s 2019, and everyone’s wondering if PBNs or Private Blog Networks are still worth building. Some would say yes, while others say no. Looking back at how it started (who can forget how Google penalized two public blog network and made them a cautionary tale?), there will always be proponents and opponents of this SEO technique. PBNs gathered steam in 2014, but people have been searching about them since 2005 based on Google Trends. It is highly likely that it has been used by many SEOs since then or even earlier. When it became the go-to strategy for grey hat SEO, the conversation went from “maybe” to “how to use PBNs effectively”. In fact, deciding which is the best solution for hosting became a critical part of building PBNs. After all, the choice of web hosting has a direct impact on whether your PBN will be flagged for a manual review. The success of PBNs, however, depends on many factors. You should first have a look at PBN introduction.

What is a PBN or Private Blog Network?

This is a network that has a number of blogs linking back to the main blog. It helps a blog rank on the top of search results, which is basically equivalent to manipulating SERPs using a number of backlinks. For this reason, search engines have developed smarter algorithms that can de-index a page using PBNs. So why bother? It provides a shortcut to ranking a page. For instance, content can be spun, cutting down the time needed to develop content. You can also use a Waybackmachine to search for blogs that have been used as PBNs and analyze the quality of their links. The process is not entirely quick and easy. But it is quicker and easier than building a blog from scratch. So, is PBN still worth building in 2019? Yes it is. You just need to be smart about it and ensure you have a good return on investment and a good return on time.

2019 PBN Best Practices

The new formula is PBNs + Outreach

Most PBN links are directed to the homepage, which will make the page highly suspicious if it becomes saturated with links. There should be links to inner pages as well. This can be achieved through outreach, where you find other websites to exchange page links with or guest posts. Building a successful PBN and evade de-indexation is not easy. But the new formula has an added a new challenge to the strategy. In the past, PBNs are the way to eliminate the need to do outreach or build relationships, which many consider a waste of time. This isn’t exactly a good thing but the focus then was to use time wisely, not outreach. 2019 is telling you something else entirely. If you look at it, outreach is the solution to strengthen PBN’s weak spot. A volume of PBNs is half the power of link building that provides short-term boosting strength. What you need is the other half that offers long-term benefits through links that continue to mature in authority and trust. So, this 2019, your blog should have a blend of PBNs and Outreach.

Optimize anchor text

The wrong anchor text makes anything look bad. So you should master choosing the right anchor text and distributing them properly. Matt Diggity of Diggity Marketing has provided a complete guide for optimization that you can use in 2019. One thing is vital, however, Anchors must look natural, resulting in variety. The more natural anchors come from your backlinks, the less likely they’ll look the same.

• Use a mix of different texts
• Use a pillow anchor with the usual Target + City anchors
• Use a diverse set of anchors--Brand Anchors, Target Anchors, Topic Anchors, URL Anchors
• Use miscellaneous phrase--”click here”, “learn more”

As for the type of distribution to use, do your homework and find out which strategy is typically used in your niche.

Avoid keyword cannibalization

• This happens when a single site has two pages or more that rank for the same keywords.
• If two or all of the pages come up for the same query a user searches, all of them are performing worse than a single page doing badly on SERPs.
• So make sure to check for keyword cannibalization. Use Ahrefs tools and refer to their cannibalization guide.

Measure link velocity

• How many new links do you need to get per unit of time to make a real difference in ranking?
• The exact number or calculation remains a hot topic for debate but nothing like a good measurement to provide you with answers.
• Track a steady drip of links per month and see if they make serious changes. Does the velocity measure accumulation at a slow or fast pace?

Link PBNs to Outreach

This practice gained popularity in 2018 and is likely to continue in 2019. It is one way to boost tier 1 (best) links by linking them with tier 2 (low-quality) links. With PBNs providing a source of links at all levels, you should employ this strategy.

Go slow with backlinks during the sandbox stage

Consider this as the probationary period for young domains. This means staying true to the whitest hat ranking factors and following Google’s guidelines like a good boy. With a young domain under close scrutiny, doing anything and everything to reach the top quickly and outrank other top sites is a recipe for disaster. The site will get stuck in the sandbox.

Recycle PBNs

Have you reached the #1 position? Rather than stop link velocity, which will put you at risk of being kicked down the rankings, you should recycle PBNs to keep backlink activity fresh and active. Many SEOs employ different strategies to make this happen.

• Kill and replace 1 link per week
• Remove 1 link and add 2 more or vice versa

With this strategy, the link profile is kept fresh minus the risk of changes that may cause penalties.

PBNs or No PBNs?

Using a private blog network is not failproof, but it does provide you with a level of control in SEO. You also get instant authority, especially when leveraging an aged and trusted website’s authority. Success won’t come easy. But employ the best PBN practices in 2019 and you will be closer to it.

Voyager 2 Became the Second Spacecraft which Reached the Outer Space

According to information published by representatives of the US space agency NASA, the Voyager 2 spacecraft, which is now at a distance of 18 billion kilometers (11 billion miles) from Earth, has reached the outer space. The data recently transmitted by Voyager 2 indicates that it has successfully “pierced” the heliosphere, the protective “bubble” of charged particles and magnetic fields that “envelops” the solar system, protecting its planets from external cosmic radiation. Let us remind our readers that the Voyager 2 was launched into space on August 20, 1977, 16 days earlier than its twin, the Voyager 1 was launched. Both Voyager mission devices carry identical scientific equipment and a Golden Record gold plate containing various sounds and a brief history of our world and civilization. Currently, the Voyager 2 has been in space for more than 41 years and 3 months, making it the longest living man-made spacecraft. Note that the mission was originally planned for a much shorter period, about five years, during which Jupiter and Saturn and the vicinities of these giant planets of our system had to be studied by the device. After the end of the main mission and the solution of all tasks, the mission’s leadership decided to send the Voyager 2 apparatus even deeper into space, to Uranus and Neptune. For this reason, some remote upgrades were carried out, which affected mainly the onboard computers and controller's software. Let us remind our readers that the Voyager 1 apparatus in 2012 became the first man-made object that managed to cross the heliosphere border of our system and enter the outer space. Now the Voyager 2 became the second spacecraft to do so, but this case provided scientists with a very large amount of valuable scientific information because they already knew in advance what they would have to face and what they should pay attention to first. The value of the data collected by the Voyager 2 increased due to the fact that its instrument Plasma Science Experiment (PSE) at the time of crossing the outer layer of the heliosphere was in a fully operational state. Note that the same tool in the apparatus Voyager 1 was malfunctioning since 1980. The PSE tool is designed to measure electric currents induced by the solar wind, which makes it possible to determine the speed, density, temperature, and pressure of the solar wind. The universe is a fascinating place, the adventures and struggles of which should be experienced with someone you love by your side, so be sure to visit this dating video chat for all of your dating needs! On November 5, the equipment of the Voyager 2 apparatus began to register a sharp decrease in the velocity of the particles of the solar wind. This is the main sign of the achievement of the so-called heliopause region, an area where the pressure of the solar wind begins to be balanced by the pressure of the interstellar medium. At the same time, other tools began to issue additional data, which served as confirmation of the above fact. Now the environment in which the Voyager 2 apparatus is located is strikingly different from everything that it has had to deal with earlier. The relatively high temperature of the solar wind has changed to the cold of a rather dense interstellar medium. Despite the fact that the Voyager 2 has already left the heliosphere, it is still quite far from the generally accepted boundary of the solar system which is located outside the horizon cloud. The Orta cloud is a massive "bubble" of particles and blocks of ice, the inner boundary of which is at a distance of 1000 astronomical units from the sun. For reference, the astronomical unit is equivalent to the average distance between the Earth and the Sun and is approximately 149.67 million kilometers. Unfortunately, the Voyager 2 will no longer be able to send images taken in interstellar space to Earth. In order to save the scarce electricity, all the cameras and other non-essential scientific instruments for the current mission were turned off. Since the Voyager mission vehicles are very far from the Sun and cannot rely on solar batteries, the main source of their energy is a radioisotope thermogenerator, the power output of which decreases by 4 watts over the course of one year.

3 Writing Projects You Can Finish in a Single Day

Writing is an art that is utilized in numerous areas of life. The same art is applied to projects that require specialized skills in research, writing, editing.

5 Main Steps in the Quick Writing Process

The following is a detailed breakdown of the general writing procedure for any project you need now:

• Have an idea of what to write about. Everything deserves proper planning and writing is not exceptional. Planning involves having a clear picture of what you intend to write about. This way you can swing into action seamlessly. Not only is this applicable in creative writing, but it also cuts across other forms of writing including official and formal. It would be easier to take note of any ideas that cross your mind in a notebook.

• Build on your idea. Ideas just give you a sketch of what you intend to come up with. The next stage of writing is to get some flesh onto your sketch. Here you undertake brainstorming and free writing which is basically expounding and actualizing your imaginations. Additionally, no editing on flow and other errors is required at this point. After compiling your random ideas, the next step would be to pick out the most appealing one that corresponds with the heading or the aim of your final draft. The ideas gathered here will form the actual book or paper.

• Begin writing a project. Now that you have the ideas and a proper plan of execution you can delve into the actual writing process. Now that this is your first draft, do not keep your focus on grammar or word count. Similarly, you should not freak out about veering off the topic. This stage involves a lot of free writing. As a matter of fact, even the best writers produce several drafts before getting it right.

• Revise your work. By this time, you should at least have one draft of your ideas. Revision involves a lot of things. To begin with, you should check whether you draft is in line with the topic. Other than that, confirm if the word count is right. In addition to that, you can rearrange the format to your liking, remove some parts that seem irrelevant or replace words and sentences with better ones.
• Edit and proofread your written content. A flawless project will be more appealing to whoever reads it. That is why you should refine your draft. No matter how perfect you may be, you are still expendable when it comes to making mistakes in one way or the other. That is why we have this stage. Look out for spelling errors, punctuation, omissions, repetitions, grammar, and clarity. In case you hire a freelancer from fast essay writing service, this might also be a great time to go through your paper and eliminate any shortcomings. Editing and proofreading is the final stage for any writing process.

Finally, a proper procedure guarantees the instant effective communication and the right course of action will direct you to quick results in writing. Rather than use 24/7 fast essay writing services to write your project, you can make use of the procedures above to create the best paper ever.

10 Engineering Writing Prompts Mastering the Written Form of Communication

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at 10 Engineering Writing Prompts Mastering the Written Form of Communication. Get surprised that engineers should be effective in writing as most humanities-minded people do? Yes, there is a problem among most specialists, who have technical knowledge. They can’t share their knowledge in a way that’s easy to understand for the audience that has no bearing on the subject. So any written paper should be clear, concise and coherent. As the world of engineering is expanding dramatically today, engineers need to develop new strategies for presenting the research ideas and results to the non-engineering audience. So how to do it effectively? You can use a lot of guidance, manuals or apply some engineering writing prompts in practice. There is no need to look for them online, all of them are given in this article. So read this article once and write a brilliant research paper or any other assignment on Engineering.

Engineering Writing: What Does It Involve?

Engineering writing differs from other types of writing as it has different purposes and characteristics. Let’s look at what will make your engineering writing different from creative writing, for example.

• Technical knowledge and skills. What abilities and knowledge needed to perform specific tasks in Engineering? You can open the article presented on The Balance Careers and make sure that most of them are practical and relate to mechanical, information technology, mathematical, or scientific tasks. Keep in mind that data analysis skills are most valued today. Focus on them while dealing with writing on Engineering.
• Technical writing style. Any piece of writing is created in a particular style. As a rule, it can be formal or informal. All academic papers are written in an impersonal style. Besides a formal way of writing, in engineering papers, you need to stick to a technical writing style. Read more about this style in this guide.
• Training and experience. Here, you can argue by stating that other specialists also need additional training to come up with effective writing. Believe that engineers should practice in writing doubly to get valuable experience to convey complex information.

10 Engineering Writing Prompts Based on a Field of Expertise

 

• Data analysis. Today, every industry relies on data that is needed to be collected, organized, and interpreted. Choose a specific area where data analysis is needed and describe in detail - what method is more reliable and why.

• Coding and programming. Program an application to perform without any error. However, on the way of coding, you may face some issues. Write a report in which you should present the initial steps of computer programming. Analyze a problem and provide the list of possible solutions to it.

• Defense system. Write a case study where you should demonstrate the understanding of the defense system of a particular country from the engineer’s perspective. Think of new technologies that would contribute to the area and why.

• Design specifications and estimates. Design a product that can be manufactured or implemented by an engineer. Describe the procedure of creating in detail.

• Civil safety. Review the construction of roads and buildings in your country or city. Evaluate it accordingly as a civil engineer.

• Control systems. Test any given technology and record all the experimental findings by describing your methodology - what you do, in what order and so on.

• Environment. Conduct a hazardous-waste management study during which you should evaluate the significance of the hazard, provide some advice on its treatment and containment, and introduce some regulations to prevent further mishaps.

• Chemistry. Examine the principles of chemical engineering to solve some problems in the production or use of chemicals in a variety of manufacturing industries - energy, food, clothing.

• Health and medicine. Provide some engineering principles and practices to solve medical and health-related problems in the 21st century. Based on medical scientists, evaluate the health management system from the perspective of instrumentation.

• Nuclear energy. Consider the future development of nuclear power sources - what expectations and risks are. Answer the main question - will be a ‘nuclear energy and radiation’ problem solved in the near future?

    If you apply all the practical materials in writing on Engineering, you'll be better able to communicate your message as an engineer who aims to make this world productive, safe and the best place to live. What is more sufficient? It is that you won’t ask anyone “Do my homework for me please” as you’ll do it on your own effortlessly. But still, if you make similar requests, it is better to get assignment help online from real experts.

Linear Actuators: How Do They Work?

Hello everyone, I hope you all are doing great. In today's tutorial, we are gonna have a look at Linear Actuators and How Do They Work? There are many types of actuators available but today we are only gonna focus on Linear actuators. If you got into any trouble then ask in comments and I will help you out. You should also try our Forum section which we have recently started and our experts will surely solve your issues. You should also have a look at How to use Arduino with Linear Actuator, if you are working on some automation project. So, let's get started with it:

What Is a Linear Actuator?

A linear actuator is a piece of mechanical equipment commonly used on industrial scale in brakes, stamping presses, and car jacks. It acts by using power to generate straight-line motion. It is achieved by employing a lead-screw that creates up and down movement by turning to the left or to the right. The direction of the movement can be regulated by using a switch that reverses motor wiring. Different actuators will have varying shafts, speeds and capacities that will change depending on the gear to suit your specific needs. How does electric linear actuator work? The answer to this question depends on the kind of instrument that you are dealing with. There are several types of actuators most commonly used in industry:

• Screw: involves movement that is manipulated by twisting screw threads;
• Wheel and handle: the movement is generated by a chain connected to the shaft;
• Cam: the movement production exploits a wedge-like apparatus.

Composition and Function

How do linear actuators work? Well, it all starts with the structural constituents of the machine. The key component is the movement-enabling motor segment that permits extremely frequent clockwise or anticlockwise rotation. The gearbox is essential to change speed and force of linear movement generated by the lead-screw: it reduces the frequency to condition for the rotation of the screw. To avoid recantation and overstretching, there might be an incorporated limit switch inside the shaft: one for the retracted position, and one for the extended position. This is facilitated by the acme drill nut that activates the switch in the middle of the vertical motion. This is followed by the cut in power supply, stopping and then reversing the movement. The flow of electricity is only permitted unidirectionally, creating polarity and switching the course. The movement in both directions is then restored. All of these processes combined ultimately dictate the speed of screw rotation and hence linear movement and outlining the electric linear actuator working principle.

Choosing an Actuator

How do electric linear actuator works? We have found the answer to this question, so now you might want to learn how to choose an actuator that will accommodate your needs. There are countless ways to utilize the mechanical functions of actuators, each having a corresponding type of apparatus. To make a sensible choice you must know the goals and objectives of your actuator project. Start by asking yourself some questions: how fast and powerful do you need it to be? How much do you want it to travel? How heavily do you intend to rely on it? You will then have to think of the weight you’ll impose on it to judge the amount of force you require. Consequently, you will pick one of the following types:

• Track actuator: generates a stable path length during stroke, hence suitable for small compartments;
• Rod-style actuator: simple shafts suitable for most applications;
• Feedback actuator: allows high precision of movement due to a sophisticated set of equipment.

You might also consider a high-speed machine. However, you must keep in mind that the faster the movement your actuator generates, the less powerful it will be, as these two properties feed off each other.

Conclusion

Linear actuators are sophisticated mechanical setups generating straight-line motion that can find many industrial and everyday applications. There are different kinds of actuators of various kinds, having different characteristics suitable for their purposes. Inside a linear actuator, there is a motor segment, a gearbox, a lead-screw, a limit switch, and an acme drill nut. These activate and regulate the direction, force and speed of motion, also detecting the kind of activity the actuator can perform.

How Scientific and Medical Animation is used

Hello friends, I hope you all are doing great. In today's tutorial, I am going to give you a detailed overview of How Scientific and Medical Animation is used. The use of scientific and medical animation is a growing trend that has a broad range of applications. Austin Visuals is a 3D and 2D animation company with a team of professionals with the technical skill and creativity to produce 3D medical animation, scientific animation, and forensic animations. Doctor’s offices, hospitals, and medical schools are turning to 3D medical animation for instructional purposes. Animation companies can create animated video clips that explain surgical procedures, medical treatments, or pharmaceutical mechanisms to patients. Animated video is engaging and easy to understand, which is particularly useful for explaining complex and unfamiliar information. Animation is increasingly being used in doctor’s offices, hospital websites, and even on television shows that are designed to educate people about health and medical topics. Animated videos can be an effective tool for providing emergency care instructions, for example, for performing CPR or first aid procedures in an emergency situation. Animated video is being used for medical and surgical instruction in a few different ways. Animation provides another way to train new doctors in anatomical and surgical topics to enhance their knowledge and understanding of complicated topics and procedures. Video is being used to teach surgical students how to perform basic procedures. Seasoned doctors use animation to expand their skill set and for surgical planning. Prescription drug websites often feature animated video to teach patients about how their medications work in the human body. Animated video clips are provided to convey information about how the company’s medication improves symptoms, the interaction between drug molecules, and even the origin of a specific disease. Scientific animation is used to convey information to students in high school, college, and graduate school, professional scientists, and the general public. Animation makes it possible to visualize processes and structures that are not visible to the human eye. Animation is being used for visualizing microscopic processes, cellular and sub-cellular processes for illustrating atomic and molecular structures. Forensics is another field that has begun to embrace animation technology. Forensic animations can be used to generate a virtual autopsy when there are damaged remains and for reconstruction of a crime scene. Law enforcement agencies are using animation to recreate crime scenes or accident scenes to solve cases and present evidence in criminal cases in court. Forensics experts must analyze and interpret evidence at a crime scene to solve criminal cases. When they present their theories in court, explaining technical information to jurors can be challenging and many jurors have trouble visualizing the theories presented in court. Forensic animations can help jurors visualize the scene to determine if assertions from the prosecution or defense are possible. The world of medical animation and scientific animation is rapidly growing and increasingly being used in medical offices, hospitals, medical schools, and even by law enforcement and in court. Choose a qualified 2D and 3D animation company with the resources and creative professionals to produce high quality animated video content that will serve your specific requirements.

Here’s Why a Master’s in Engineering Worth It

Hello friends, I hope you all are doing great. In today's tutorial, I am going to tell you the importance of Master’s in Engineering. You don’t need a master’s degree to get a good job in engineering. Talented engineers are in high demand, and plenty of young engineers are bringing home nice paychecks and enjoying good job prospects with nothing more than a bachelor’s degree in an engineering field. And, as hard as it was to earn your bachelor’s, do you really want to go on for an advanced degree in engineering? While you may not necessarily need a master’s degree to get a job in engineering, there are a lot of good reasons why earning this credential might be worth it. There are the obvious salary benefits, but it isn’t just a higher salary that makes an engineering master’s a good job option. You’ll qualify for more jobs, have greater job security and put yourself in the best position to stay up-to-date in your skills.

You’ll Make More Money

Of course, your salary as an engineer will depend somewhat on your specific field. For example, the median salary for chemical engineers with a bachelor’s degree is about $72,000, while it’s about $104,000 for electrical and computer engineers with the same credential. A master’s degree, however, will net you an average of $19,000 more a year — and you’d have trouble fitting that in your change jar, especially since it can add up to a cool half-million by the time you reach retirement. Even considering the opportunity cost of leaving the work force for a year to go back to school, your new, higher salary will allow you to recoup the costs of your degree within a decade. That’s assuming you do leave the workforce, however. Professional master’s degrees in fields like engineering are getting more popular, precisely because students today no longer have to leave the work force to go back to school. You can earn a Masters of Mechanical Engineering online; if that’s not your field, no worries — many reputable schools offer online MS in Engineering degrees in a range of engineering specialties. As an online student, you might even qualify for tuition assistance from your employer, enabling you to get a free or deeply discounted degree.

You’ll Have More Prospects

Not only will you be able to command a higher salary with a master’s, you’ll also qualify for more jobs. It’ll be easier to advance in your career, whether you want to move up in your company or pursue a new position elsewhere. Many employers now want candidates with master’s degrees, and the extra credential will help you stand out from the crowd, especially in saturated fields like mechanical engineering.

You’ll Be More Recession-Proof

A few years ago, you may not have given a master’s degree a second thought. But these days, it’s increasingly important to think about your long-term employability. You need to keep your skills fresh and prepare yourself to address not just the problems facing your industry today but those that are bound to come up in the future. A master’s in engineering offers you that path to greater job security.

Rise to the Cutting Edge of Research in Your Field

It’s true that a master’s degree may not enhance your job prospects that much if you’re fresh out of college — unless you specifically look for employers who value that advanced degree and have the budget to pay candidates accordingly. If you’ve been out of school for a few years, or even a few decades, earning a master’s will teach you how to work with the newest technology in your field. You’ll be able to prove to employers that you can grapple with the latest research, equipment and software. A master’s will freshen up your skills and give you the tools to stay competitive, even as colleges and universities around the country crank out new engineering graduates faster and faster. If you want to ensure that your skills stay fresh and your career stays fulfilling, stable and promising, you need to earn a master’s degree. A master’s in engineering shows employers that you have the skills and discipline to stick with a difficult project long-term and that you’re really committed to wringing every last drop of potential out of your career. Don’t wait any longer — the sooner you start master’s classes, the sooner you can reap the rewards of a more advanced degree.

Interfacing of Arduino with 74HC595 & 74HC165

Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Interface Arduino with 74HC595 & 74HC165. I have already interfaced these shift registers separately with Arduino. In the first tutorial we have seen Arduino 74HC595 Interfacing in which I have discussed How to increase the output pins of Arduino using 74HC595. After that in second tutorial we have seen Arduino 74HC165 Interfacing where we have increased the input pins of Arduino. So, now we are gonna interface both of these shift registers with Arduino UNO and will increase both input and output pins of Arduino. I have also given the Proteus simulations for download at the end of this tutorial along with Arduino code. So, lets get started with Interfacing of Arduino with 74HC595 & 74HC165:

Interfacing of Arduino with 74HC595 & 74HC165

• First of all, you need to design a Proteus Simulation as shown in below figure:

• As you can see in above figure, I have used 74HC165 & 74HC595 and interfaced its pins with Arduino UNO.

• I could use same clock for these shift registers but it would have made the code quite complex.
• That's why I have used separate clock pins and I have used the below code to reflect the input on output.

#define NUMBER_OF_SHIFT_CHIPS   1
#define DATA_WIDTH   NUMBER_OF_SHIFT_CHIPS * 8
#define TotalIC 2
#define TotalICPins TotalIC * 8

int LoadPin    = 8;
int EnablePin  = 9;
int DataPin    = 11;
int ClockPin   = 12;

int RCLK = 5;
int SER = 6;
int SRCLK = 7;

unsigned long pinValues;
unsigned long oldPinValues;
boolean Data[TotalICPins];

void setup()
{
    Serial.begin(9600);

    pinMode(LoadPin, OUTPUT);
    pinMode(EnablePin, OUTPUT);
    pinMode(ClockPin, OUTPUT);
    pinMode(DataPin, INPUT);

    digitalWrite(ClockPin, LOW);
    digitalWrite(LoadPin, HIGH);
    Serial.println("Visit us at www.TheEngineeringProjects.com");
    Serial.println();
    pinMode(SER, OUTPUT);
    pinMode(RCLK, OUTPUT);
    pinMode(SRCLK, OUTPUT);

    ClearBuffer();
    
    pinValues = read_shift_regs();
    print_byte();
    oldPinValues = pinValues;
}

void loop()
{
    pinValues = read_shift_regs();

    if(pinValues != oldPinValues)
    {
        print_byte();
        oldPinValues = pinValues;
    }

}

unsigned long read_shift_regs()
{
    long bitVal;
    unsigned long bytesVal = 0;

    digitalWrite(EnablePin, HIGH);
    digitalWrite(LoadPin, LOW);
    delayMicroseconds(5);
    digitalWrite(LoadPin, HIGH);
    digitalWrite(EnablePin, LOW);

    for(int i = 0; i < DATA_WIDTH; i++)
    {
        bitVal = digitalRead(DataPin);
        bytesVal |= (bitVal << ((DATA_WIDTH-1) - i));

        digitalWrite(ClockPin, HIGH);
        delayMicroseconds(5);
        digitalWrite(ClockPin, LOW);
    }

    return(bytesVal);
}

void print_byte() { 
  byte i; 

  Serial.println("*Shift Register Values:*\r\n");

  for(byte i=0; i<=DATA_WIDTH-1; i++) 
  { 
    Serial.print("P");
    Serial.print(i+1);
    Serial.print(" "); 
  }
  Serial.println();
  for(byte i=0; i<=DATA_WIDTH-1; i++) 
  { 
    
    Serial.print(pinValues >> i & 1, BIN); 
    Data[i] = pinValues >> i & 1, BIN;
    //if(BinaryValue == 1){Data[i] = HIGH;}
    //if(BinaryValue == 0){Data[i] = LOW;}
    UpdateData();
    if(i>8){Serial.print(" ");}
    Serial.print("  "); 
    
  } 
  
  Serial.print("\n"); 
  Serial.println();Serial.println();

}

void ClearBuffer()
{
    for(int i = TotalICPins - 1; i >=  0; i--)
    {
       Data[i] = LOW;
    }
    UpdateData();
} 

void UpdateData()
{
   digitalWrite(RCLK, LOW);
   for(int i = TotalICPins - 1; i >=  0; i--)
   {
        digitalWrite(SRCLK, LOW);   
        digitalWrite(SER, Data[i]);
        digitalWrite(SRCLK, HIGH);

  }
  digitalWrite(RCLK, HIGH);
}

• In the above code, I have used Number_of_Shift_Chips 1 and it means I am using 1 chip each, so in total 2 chips.
• Now get hex file from Arduino software and upload it in your Proteus software.
• Run your simulation and if everything goes fine then you will get something as shown in below figure:

• You can see in above figure that all those LED outputs are ON which has HIGH inputs.
• I have also attached a Virtual Terminal with Arduino to have a look at the input bits.
• Now let's add 2 chips of 74HC165 and 74HC959, so design a simple simulation as shown in below figure:

• Now in your above code change the Number of Shift chips from 1 to 2, as now we are using 2 chips each.
• Upload your hex file and if everything goes fine then you will get similar results:

• So, that's how you can easily increase input and output pins of Arduino UNO.
• I have just designed a simple code but you can work on it and can control these inputs separately as well.
• You can interface different digital sensors on these input pins and can control motors, relays, solenoids etc. at output pins.
• You can download both of these Proteus Simulations along with Arduino code by clicking the below button, but I would suggest you to dwsign it on yoru own so that you could learn from mistakes.
