optimized and efficient heat exchangers, by keeping reduced mass and dimensions of the existing heat exchangers and also keep same cooling fans, instead to re-invent the cooling devices. This paper proposes a new design of a heatsink to address such thermal challenges with the laminar forced convective heat transfer on a

Introduction Ultrasound is acoustic energy with a frequency at about 20kHz which is above the capability of human hearing. It is more commonly used in the medical field than food industry. In the medical field, the most significant usage of ultrasound is in sonographic scanners. As these scanners work at 2-18MHz, it produces smaller wavelength which is able to make sonogram of smaller details. As such, ultrasound sound based imaging technique is used to visualize body structures and tissues (Carovac

Scanner Scanner is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display. Scanners come in many types for scanning black-and-white or color. Some of the main types of scanners are described below; (Hewawithana, 2012) • Flatbed scanners: Flatbed scanners are some of the most commonly used scanners as it has both home and office functions. The way they scan documents is that a mechanism rolls under the document to obtain

Introduction Hot stamping (HS) is an advanced manufacturing technology which processes high strength part like steel at high temperatures by forging and treated by rapid-cooling rate in dies. By using hot stamping process can save a large number of equipment fees and get a good performance, for it combines forming and hardening processes in one step. As the high strength material has very good formability at high temperatures, it is achievable that complex shapes can be formed in one single operation

Independent variable the independent variable for the experiment is the temperature changing and the water melting. The dependent variable the dependent variable for the Controlled variable is the box, and the temperature of the hot water before it is going to be placed in the lunchbox and the size of each lunchbox. Problem For me enjoying a perfect lunch is to have a perfect meal. All, meals need to be either cooled or heated. Without it, many people can’t enjoy food like they do at home

When you sit and see the outdoor industry being flooded with all these new cooler brands, you wonder what really sets the coolers apart? After all they are still just and insulated box or cup that keeps you drink cold. The main difference between the different brands is the type of insulation or the quality of the seals and workmanship to make a quality product that allows little energy to escape. There are a few questions that we have that we hope to find the answer too hear they are in the following

The development and application of nanomaterials has allowed society and the environment to benefit in many ways. Nanomaterials are three-dimensional objects that have one of their dimensions in the range of 1-100nm. They can exist in nature or be created from pre-existing materials. Their exceptionally small size means that nanomaterials possess unique physical, chemical and mechanical characteristics that might otherwise not exist with the same materials on a larger scale. In some cases, nanomaterials

Is the lack of space your excuse for not hosting a barbeque party? Or does the tedious work that comes with cleaning up put you off? If you said yes to any of the questions above, then read on to find out just how you too can become a pro in barbequing. To become the best, you must invest in a great cooker that will not only serve its purpose but will also live long doing so. Below is an overview of some of the leading brands in the industry to help you choose the best-infrared grill under $500

CHAPTER 1 INTRODUCTION Composite materials are the engineering materials made from two or more constituent materials they remain separate and distinct on a macroscopic level but forming a single component or Composites can defined as materials that consist of two more chemically and physically different phases separated by a distinct interface(matrix phase and dispersed phase). The different systems are combined judiciously to achieve a component with more and more useful structural or functional
