The thermal performance of three-dimensional integrated circuits is influenced by a number of design and technology parameters. However, the relationship between these parameters and thermal behaviour of die stacks is complex and not well understood. In this paper, we perform a detailed evaluation of the influence of stack composition and depth, thickness of dies, physical location of power dissipating...
Continued scaling of transistors and metal interconnects have resulted in high current densities and significant Joule heating in the metal lines, exacerbating thermally driven reliability issues in microprocessors. It is imperative, therefore, to develop an accurate and rapid predictive thermal characterization capability for on chip interconnect arrays to facilitate chip design. This is a multi-scale...
In industries now a day the control of chemical process is important craft. Mostly all the chemical process are highly nonlinear in nature this cause instability of the process. This paper deals with basic simulation studies on of the interactive thermal process. The Combination processes of Continuous stirred tank reactor (CSTR) and heat exchanger were controlled and the mathematical model was developed...
Passive systems, which completely depend on natural phenomena such as gravity, conduction and convection to accomplish the safety functions, are increasingly being used in new generation nuclear reactor designs. However, since the driving forces of passive systems are weak, they are more vulnerable to associated uncertainties and there may be a non-zero probability for the system to deviate from the...
Many of the components used extensively in today's handheld market are beginning to migrate from traditional lead frame design to leadless or non leaded. The primary driver for handheld manufacturers is the saved PC board space created by these components' smaller mounting areas. In addition, most components also have reductions in weight and height, as well as an improved electrical performance....
The main objective of study is to control the emission from diesel engine and improve the performance by using the emulsified fuel. A single cylinder, water cooled, four stroke diesel engine was used for this study. Experiments were conducted in the first phase at different ratios of emulsions via (50%diesel + 50 ethanol), (60% diesel + 40% ethanol), (70% diesel + 30 % ethanol) as fuel. From the investigation...
This paper presents a proactive spatiotemporal power multiplexing method to manage the thermal field in many-core processors. We first analyze the thermal field in many core processors in deep nanometer (to 16nm nodes). We show that the thermal field in many-core can have significant spatiotemporal non-uniformity along with high maximum temperature. For better reliability and improved cooling efficiency,...
Numerous online services and applications for smart devices exist today on the internet which claim almost similar functionalities. This inevitably leads to the problem of being able to choose the right one which is mostly done today by trial-and-error. However this gets tricky if it involves sharing privacy sensitive information with the service e.g. in the case of health and well-ness services....
