Pages: 1 - 5
Robust, high performance oscillator design in CMOS technology continues to pose interesting challenges. CMOS circuitry in VLSI dissipates less power during static, and is denser than any other implementations having the similar functionality.This paper provides a new approach for the physical design of ring and differential LC oscillator are designed with CMOS 45 nm technology with Microwind 3.5 EDA tool.

Pages: 6 - 8
Risk Management comprises of identification of risk, quantitative or qualitative assessment of risk, selecting the most suitable method for handling risk then proper monitoring and documentation of risk. The risk may occur due to various technical, social and political reasons. Therefore an effective system to assess and manage the risk in construction companies is a challenging task for a civil engineer. In this paper various risk factors are identified and a survey is taken among the persons present at the construction site of different companies. Some risk management policies are suggested to overcome the spotted issues and provide a risk free environment.

Pages: 9 - 16
The heat released from the flat surface is cooled by the use of jet impingement technique. The heat flux from the isothermally heated flat surface due to two-dimensional turbulent twin oblique confined slot-jet impingement is studied numerically using the ANSYS FLUENT software. Initially the flow and thermal fields for a normal confined slot-jet impingement are investigated using the RNG k-ε model and the SST k- ω model. The local Nusselt number distribution predicted by the SST k-ω model agrees notably better with the existing experimental data. Subsequently, the SST k-ω is employed to study the twin oblique impinging jet heat transfer problem. The study is conducted by varying the jet exit Reynold number, the jet to jet separation distance, jet -exit to target plate distance and the inclination angle of the jet to the impingement. Results indicate that impingement angle is reduced from 90o, the peak Nusselt number at the impingement surface is gradually reduced and its location slightly shifts away from the axis with slight decrease of the average Nusselt number for any combination of Re, L, H. The average Nusselt number is a direct function of the Reynold number and the impingement angle and is inverse function of the jet to target plate separation distance.

Microstructural Investigation of Aged Modified 9Cr-1Mo Steel Welded Joints Correlating Creep Behaviour

Mechanical Engineering
Year: 2016, Volume:2, Issue : 10
Pages: 17 - 23
There has been a constant search for new materials for high temperature applications, such as for parts of steam generators, parts of thermal power plants, piping of liquid metal reactors, which are likely to be exposed to temperature 5500c and above. Good strength and ductility values possessed by special steels make them the first choice of designers for applications mentioned. Modified 9Cr-1Mo steel has been in use for such applications since a decade. For any given material, along with the mechanical properties, there is a need to determine the creep property if the material is the choice for high temperature service applications. Further, as it has been experienced that the welds are likely zones of failure, under extreme conditions of load and temperature, probing the creep property of the welded joints of a given material becomes an important aspect of research.Hence it is proposed to probe into the creep resistance aspect of the welded joints of 9Cr-1Mo steel under different conditions of load and temperature. It is also proposed to age the samples of 9Cr-1Mo steel under different conditions so that variation of creep properties in both the parent and the weld metal can be studied adopting the indentation creep test methodology. Experiments will be designed to extract all possible information regarding structural disintegration of the material. Additionally, scanning electron microscopy is planned to be adopted to observe micro-structural changes and correlation will be attempted to link them to observed creep behaviour.

Pages: 30 - 38
The removal of zinc from aqueous solution by adsorption on Ulva lobata sp. was studied as a function of contact time, pH of the solution, metal ion concentration, adsorbent concentration and adsorbent size. Batch experiments results showed that the adsorptive capacity of Ulva lobata sp. was 13.8 mg/g of adsorbent. The Langmuir and Freundlich models were used to describe the adsorption equilibrium of zinc on Ulva lobata sp. and the adsorption followed the Langmuir isotherm. The Langmuir and Freundlich constants for adsorption of zinc on Ulva lobata sp. were determined. The pseudo first and second order rate expressions were used to correlate the experimental data. The kinetic constants were determined for both the models and the second order rate expression was found to be more suitable.

Pages: 44 - 48
The paper presents an application of data mining for improving the accuracy of prediction of a disease state by selecting the most relevant features associated with it. The experiments are performed on chronic kidney disease (CKD) data. The basic idea in this study is that use of a number of methods instead of a single one increases the probability of selecting features which are more closely related to the disease. Multiple feature selection methods have been applied independently on the CKD data set and the results integrated into a final optimal set of features. These data have been applied to the classifiers to identify CKD from reference cases. Various classification methods are compared to select the best model over 10-fold cross-validation in the training data set. Random Forest classifier is chosen as the best model with superior performance.

As we are surrounded by variety of post-PC devices, the traditional methods for identifying and authenticating users have become time-consuming. We present a system that will provide a capacitive communication method through while a product can identify who is interacting with it. This method exploits the capacitive touchscreens, which are now reached-down in laptops, mobile, and tablets, more as a signal receiver. The signal that identifies the user can be generated by a small transmitter placed into a ring, watch, or other artifact carried on or into the human body.

Due to migration of data from local storage to cloud number of Wi-Fi users are increased. On wireless network numbers of users get increased and the speed get reduced uniformly. As per IEEE 802.11n Wi Fi provide us speed up to 150-160 Mbps. It is still deficient to accommodate desired no of users. To remedy this restriction, we are presenting the idea of Li-Fi. As per German scientist Harald Haas -Transmitting data through a light-emitting diode light bulb that varies in intensity quicker than the human eyes can follow it. Haas says his discovery, which is called as D-LIGHT, able to make data rates quicker than 10 Mbps, which is speedier than the placed for typical broadband. As we know twentieth century is an epoch of internet. Where so many communications take place over the internet. Wi-Fi is most ordinarily used in the present century for establishing connection with the internet. In Wi Fi the speed of data transferring and the amount of users can use, are restricted. Our project is about visible light is a high speed, duplex and absolutely networked sections of communication. Where light comes in use as a medium for sending the messages. As we know the speed of the light is approximately 3x108 m/s which is going to act as a medium that will offer the incredible speed for data transmissions. Not only speed however also the protection in a closed surroundings will increase with the use of Li-Fi. Our project aims at ascertaining the use of Li-Fi also branded as Optical wireless communication.
