Design Considerations for Secure Embedded Systems

2020-08-05
Embedded hardware is everywhere you look today from your vehicle’s infotainment system to refrigerator to medical devices and everything else in-between. With so much exposure one would think that such devices are secure against attack; however, sadly for many devices this is not the case. For proof, just look no further than your local news reports. They are full of reports on devices being hacked. So, as engineers, how do we go about first identifying and mitigating (or capitalizing) the potential security vulnerabilities within these devices?

Automobile Exhaust Emmision Control- A review

2019-11-21
2019-28-2382
Since the 20th century increase in the number of cars in the major cities is been a point of concern because of the toxic gasses being emitted from the engine of an automobile. These gasses are polluting the atmosphere and degrading the air to breathe. The main gasses responsible for the degradation of air quality are carbon monoxide, hydrocarbon and oxides of nitrogen. There is a necessity to find ways to reduce the pollution emitted into the atmosphere from the automobile. The source of emission is either evaporation from fuel tank or carburetor which is easy to be dealt with or harmful gasses due to improper combustion which is a concern for the environment. The two ways to reduce these emissions are, modification in the engine to minimize the production of harmful gases and to treat the harmful gasses emitted from the engine before blowing it into the atmosphere from the exhaust. Catalysts help to break harmful gasses into smaller compounds that are environment-friendly.

Prospects of Bio Diesel and blends as a fuel supplement for diesel engines.

2019-11-21
2019-28-2393
Biodiesel can supplement petroleum product as a "perfect vitality source". It can ensure nature by diminishing CO2, SO2, CO, HC emission to an extent. The carbon cycle of Biodiesel is dynamic through the photosynthesis procedure .Plants ingest CO2, or, in other words those released by the biodiesel ignition process. Utilizing biodiesel can all the more adequately lessen the outflow of CO2, secure the indigenous habitat and keep up the environmental equalization, contrasted with the utilization of petroleum product. This paper considers the issues and gives understanding on the utilization of bio diesel in existing passenger vehicles which runs on diesel as a fuel. Because of increment in use of non-renewable energy sources viz., petroleum products are on an exponential decline. Today we have an option of electric vehicle or fuel cell based vehicles but what about the existing infrastructures of Billions of vehicles plying on Indian road. Bio diesel as a fuel solves this issue.

2019-28-2461
Keywords-Coolant,Ventilation Research and/or Engineering Questions/Objective: Number of Occupants is the major parameter when we consider Air Conditioning System. The number of person who stays in the room may vary in the same way the person who travels in the automobile also vary throughout the distance. This is more prevalent in transportation system like bus, train and where lot of people will travel together and where dropping station in the vehicle is too frequent.In this type,operating A.C has to be varied Methodology: . Instead the number count in the vehicle will be monitored from time to time. Based on the number of count, the cabin has to be cooled or heated and accordingly corresponding power has to be drawn by the compressor from the engine. This human count can be detected based on the number of CO2 sensor located in the cabin. the amount of fresh air that should be added to a cabin can be controlled by a carbon dioxide level transmitter.

Experimental investigations on CO2 recovery from petrol engine exhaust using adsorption technology

2019-11-21
2019-28-2577
Energy policy reviews state that automobiles contribute 25% of the total Carbon-di-oxide (CO2) emission. The current trend in emission control techniques of automobile exhaust is to reduce CO2 emission. We know that CO2 is a greenhouse gas and it leads to global warming. Conversion of CO2 into carbon and oxygen is a difficult and energy consuming process when compared to the catalytic action of catalytic converters on CO, HC and NOX. The best way to reduce it is to capture it from the source, store it and use it for industry applications. To physically capture the CO2 from the engine exhaust, adsorbents like molecular sieves are utilized. When compared to other methods of CO2 separation, adsorption technique consumes less energy and the sieves can be regenerated, reused and recycled once it is completely saturated. In this research work, zeolite X13 was chosen as a molecular sieve to adsorb CO2 from the exhaust.

A review on influence of different flushing methods on Material Removal Rate using EDM.

2019-11-21
2019-28-2543
Electrical release machining (EDM), is a material removal procedure whereby a coveted shape is acquired by utilizing electrical releases (sparks). Material is expelled from the work piece by a progression of quickly repeating current releases between cathode and anode, isolated by a dielectric fluid and subject to an electric voltage. At the point when the voltage between the two terminals is expanded, the power of the electric field in the volume between the anodes winds up more prominent than the quality of the dielectric (in any event in a few spots), which separates, enabling current to stream between the two cathodes. This wonder is the equivalent as the breakdown of a capacitor (condenser). Accordingly, material is expelled from the cathodes.
