Authors- PARAG NANDI, ALEX C VARGHESE, MADHAB CHANDRA DAS, PAMELA BANERJEE, NABENDU MURMU, SUDIP K BANERJEE
Abstract- This study is to evaluate the levels of heavy metals, such as Pb (Lead), Cd (Cadmium) and As (Arsenic) in seminal plasma and its correlation with semen parameters such as volume, concentration and motility. This study is specifically focused on in vivo effects of heavy metals on total seminal and sperm cell quality. Semen samples were collected from male partners of infertile couples. Heavy metal constituents of seperated seminal plasma was been analyzed by atomic absorbtion spectrophotometry and corresponding seminogram was done according to WHO guidelines. It has been found that In normozoospermic subjects Pb level in seminal plasma was below detectable limit compared to the subnormal samples. Similarly subjects having less seminal volume, showed considerably higher amount of Cd in their seminal plasma, compared to the subjects having normal seminal volume. Among the three heavy metals Cd concentration was also found to be much higher in all subjects. Samples having considerable motility problems had significantly high concentration of As. Recent studies have suggested that, exposure to certain chemicals is associated with reproductive toxicity including changes in semen parameters.

3. INTRUSION DETECTION AND PREVENTION SYSTEM FOR CLOUD SIMULATION ENVIRONMENT USING HIDDEN MARKOV MODEL
Authors- CINU JOSEPH, ANILA THOMAS, VINCE PAUL, SANKARANARAYANAN P N
Abstract- Any activity aimed at disrupting a service or making a resource unavailable or gaining unauthorized access can be termed as an intrusion. Intrusion detection systems (IDSs) play a key role in detecting such malicious activities and enable administrators in securing network systems. The cloud computing platform gives people the opportunity for sharing resources, services and information among the people of the whole world. In private cloud system, information is shared among the persons who are in that cloud. For this, security or personal information hiding process hampers. In this paper we have proposed new security architecture for cloud computing platform. This ensures secure communication system and hiding information from others by authentication using shared secret key MD5 and provides security using Hidden Markov Model. This structure can be easily applied with main cloud computing features, e.g. PaaS, SaaS and IaaS. Our work mainly deals with the security system of the whole cloud computing platform.
Keywords: Cloud Computing, Intrusion detection and prevention system, MD5 Hashing, Hidden Markov Model.

Authors- N.M. GIREESH, N.R. BANAPURMATH, V.S. YALIWAL, R.S. HOSMATH, P.G. TEWARI
Abstract- This paper presents the performance,combustion and emission characteristics of a single cylinder four stroke water cooled5.2 kW running at 1500 RPM diesel engine operated on CNG, Hydrogen blended compressed natural gas, (HCNG)‐ methyl esters of Honge oil (H) and methyl esters of Jatropha oil (J) combinations. The performance of the biodiesel‐HCNG fueled engine was optimized in terms of compression ratio, injection timing and exhaust gas recirculation (EGR) and was compared with base line diesel‐HCNG operation. The engine performance was found to be better with increased compression ratio, advanced injection timing and appropriate percentage of EGR(5%) for the tested fuel combinations. Compared to diesel‐HCNG baseline fuel combination, the methyl esters of Honge and Jatropha oil‐HCNG operation resulted in overall poorer performance. Performance of the dual fuel engine was further enhanced for optimized engine conditions of 17.5 compression ratio, 270bTDC injection timing and 5% EGR. The CNG enriched fuel and biodiesel combinations showed nearer to diesel‐HCNG combination performance in terms of brake thermal efficiency, combustion parameters and emission levels.

Abstract- Water, food, energy and the environment have got intertwined in a spiral of decline and degradation .The challenge is to slow the spin and reverse the direction. The world’s thirst for water is likely to become one of the most pressing issues of the 21st century. Rapid pace of industrialization, concurrent growth of urbanization, need and change of life style of ever expanding population have the potential to damage the environment and degrade the available surface and ground water sources. Since there has been growing concern about pollution in Angul‐Talcher area due to industrial, mining and other anthropogenic activities, Central Pollution Control Board and Ministry of Environment & Forests have identified this zone as one of the hot spots in respect of pollution hazards. The present study is an attempt to provide a qualitative and quantitative status indicating the suitability of water sources for drinking purpose. The study on seasonal variations of physic‐chemical characteristics along with its water quality of ground water resources fluctuated from one season to other making the sources unfit for human consumption. Water Quality Index (WQI) values for ground water in different seasons has been calculated to classify the sources according to pollution level and suitability for drinking water purpose.

Abstract- Security is not guaranteed in Wireless ad hoc network because of its unstable infrastructure. This network suffers from various attacks; here in this paper we deal with wormhole attack. Wormhole is identified base on the fact that transmission time between two fake neighbours created by wormhole is considerably higher than that between two real neighbours which are within radio range of each other. Many techniques are used to detect wormhole attack but they do not efficiently remove the wormhole. In this paper we propose efficient mechanism named TTM and PDM to detect the wormhole attack efficiently.
Key Words – Admission control, mobile ad‐hoc networks, Quality of Service, ad hoc routing.

14. VULNERABILITY OF THE R.C.BUILDINGS SITUATED IN SEISMIC ZONE II REGION
Author- Dr. MOHD. HAMRAJ
Abstract- Recent earthquakes in the Indian state Gujarat earthquake on January 26, 2001 with a magnitude of 7.6 on Richter scale have led to an increase in the seismic zoning factor over many parts of the country. Under such circumstances, seismic qualification of existing buildings has become extremely important. Seismic qualification eventually leads to retrofitting of the deficient structures. The most of the Buildings in the Hyderabad, India were constructed by taking overhangs as an exterior part of the Building, although this increases the floor area of the Buildings. All most every R.C framed structures have overhang portions; the main disadvantage of the overhangs is they are very weak in nature. The Hyderabad city comes under seismic zone II region which is considered as very low zone based on the seismic zones of India. So the structures are constructed without considering the earthquake forces. The need of this work is to identify the vulnerability of such buildings.

17. FILAMENTATION INSTABILITY OF AN ELECTROMAGNETIC WAVE IN UNMAGNETISED EXPANDING PLASMA
Author- GHANSHYAM
Abstract- A laser beam propagating at an angle to the density gradient in expanding plasma is susceptible to filamentation instability. For a linear density profile and self‐consistent temperature and expansion velocity profiles, the amplitude of the perturbation grows as an airy function with the distance of propagation. The characteristic growth length decreases with the size of perturbation and the ratio of expansion velocity to sound velocity. It increases with the angle laser k vector makes with the density gradient. The spatial growth of perturbation of lager size starts occurring deeper into the plasma.

19. AUDIO COMPRESSION USING DCT & CS
Authors- SUSHILKUMAR BAPUSAHEB SHINDE, PROF. RAKESH MANDLIYA
Abstract- A large amount of techniques have been proposed to identify whether a multimedia content has been illegally tampered or not. Nevertheless, very few efforts have been devoted to identifying which kind of attack has been carried out, especially due to the large data required for this task. We propose a novel hashing scheme which exploits the paradigms of compressive sensing and distributed source coding to generate a compact hash signature, and we apply it to the case of audio content protection. At the content user side, the hash is decoded using distributed source coding tools. If the tampering is sparsifiable or compressible in some orthonormal basis or redundant dictionary, it is possible to identify the time‐frequency position of the attack, with a hash size as small as 200 bits/second; the bit saving obtained by introducing distributed source coding ranges between 20% to 70%. The audio content provider produces a small hash signature by computing a limited number of random projections of a perceptual, time‐frequency representation of the original audio stream; the audio hash is given by the syndrome bits of an LDPC code applied to the projections. By using the DCT as signal preprocessor in order to obtain a sparse representation in the frequency domain, we show that the subsequent application of CS represent our signals with less information than the well‐known sampling theorem. This means that our results could be the basis for a new compression method for audio and speech signals.

Authors- DEEPENDRA SINGH BHATI, GHANSHYAM
Abstract- Developments in large scale integration resulted in millions of transistors placed on a single chip for execution of intricate circuitry. Due to this placing of large no of transistors within a small area resulted in more heat dissipation and power consumption. To solve these problems many research were carried on and solutions were proposed such as by decreasing the power supply voltage, switching frequency and capacitance of transistor. Different designs of Manchester Encoder has been designed using CMOS inverters, Transmission Gates, NMOS switches, Pass Transistors & GDI (Gate Diffusion Input) cell that can be operated at higher frequencies. All designs have been designed using 32nm UMC CMOS technology and compared at 1GHz, 2.5GHz & 5GHz clock frequency and experimental results show a correct behaviour up to 5 GHz.

Authors- LAYTH MOHAMMED, MOHAMED.N.M.ANSARI, FEI‐LING PUA
Abstract- During the last century, that the natural fiber reinforced polymer composites have become an attractive economically and ecologically composites .Oil palm fiber (OPF) reinforced epoxy composites which can be used in several applications like car industry and constructions were manufactured casting methods. In particular, the effects of alkaline treatment, silane treatment and acetyl treatment were investigated for 30 wt% of OPF reinforced epoxy composites. The tensile test and scanning electron microscopy (SEM) were carried out to determine the effect of chemical treatment on the mechanical properties of the composites. The results showed that chemical treatments on the fibers can enhance the tensile strength of its composites. Improvements are governed by the removal of hemicellulose and lignin from the fiber, which provides a platform for better chemical reactions between fibers and matrix. Silane treated OPF /epoxy composited achieved high mechanical properties compared to untreated and another treaded epoxy composites.

22. IMPROVING THE MUTUAL CACHING SERVICE FOR DATA ACCESS IN DISRUPTION TOLERANT NETWORK WITH COOPERATIVE POSITIONING AND TRACKING
Authors- V.SARANYA, H.PRABAVATHI
Abstract- Disruption tolerant networks (DTNs) are portraying by low node frequency, unreliable node mobility and lack of global network information. Most of current research efforts in DTNs focus on data promote, but only limited work has been done on providing efficient data access to users. Support for cooperative caching in DTNs is a novel approach which enables the sharing and distribution of cached data among multiple nodes and reduces data access delay. The fundamental idea is to intentionally cache data at a set of network central locations (NCLs), which can be easily accessed by other nodes in the network. A NCL selection based on a probabilistic selection metric and coordinates multiple caching nodes to optimize the trade-off between data accessibility and caching overhead. In DTNs the current position of the nodes and also their transition can be tracked by the PulseCounting and ProbTracking technique. This process has the similar technique like GPS.

Authors- ANNU, URMILA, ARCHANA GARG
Abstract- Heavy metal content of industrial soil samples was measured to access degree of contamination in Rohtak city and likelihood by which this contamination can be remobilized. Heavy metal concentrations were determined for soil samples by (EC Electronics Corporation of India Limited) AAS‐4141. Soil samples at four polluted sites were collected at a depth of 5, 10, 15 and 20 cm. It was found that Cu level varies from 3.95 to 5690 mg/kg which decrease rapidly with depth. Concentrations of different profile samples show that different metals concentrate at different depths but largely concentrated in top 15cm soil. The soil physiochemical properties like pH, electrical conductivity and TDS were also determined. The soil pH was found to vary from 6.61 to 9.39 at site R, 7.1to7.9 at site S, 7.89 to 11.4 at site T, 7.13 to 8.32 at site U; electrical conductivity varied from 0.372 to 4.32 mS at site R, 0.335 to 3.03 mS at site S, 0.538 to 6.67 mS at site T, 0.692 to 3.43 mS at site U and TDS varied from 0.251to2.59 ppt at site R, 0.328 to 1.946 ppt at site S, 0.338 to 4.43 ppt at site T, 0.446 to 2.24 ppt at site U. The concentration level of different metals varied with depths like Pb varied from 209.25to 832.5 mg/Kg; Cu from3.95 to 5690 mg/Kg; Zn from1.5 to 160.50 mg/Kg; Cd from 10.35 to 26.70 mg/Kg and Ni from 52.80to 497.15 mg/Kg. The interplay of soil physiochemical properties and soil concentration is discussed in details. From correlation analysis it was found that pH, conductivity and TDS were important factors in controlling distribution of heavy metals in the soil at various depths. As assessment of heavy metal mobility in soil is complex but highlighted factors have strong influence in variation of metal accumulation in soil is also discussed.

In these samples concentration of Cu is found to vary between 62.77 mg Kg‐1 ‐ 1.14 mg Kg‐1 of soil; Zn is found to vary between 94.69 mg Kg‐1 ‐ 3.42 mg Kg‐1 of soil; Cd is found to vary between 2.37 mg Kg‐1 ‐ 1.03 mg Kg‐1 of soil; Pb is found to vary between 115.8 mg Kg‐1 ‐ 3.11 mg Kg‐1 of soil and Ni is found to vary between 59.79 mg Kg‐1 ‐ 11.2 mg Kg‐1 of soil. Lead concentration was maximum and Cadmium was minimum in soil samples. Hisar road is more polluted than Jind road with Pb, Cu, Ni and Cd. Contamination of soil by heavy metals is in the order Pb>Zn>Ni>Cu>Cd. Pearson’s correlation coefficient was applied on physicochemical parameters with heavy metals. Results showed negative correlation of Cu, Pb, Cd and Ni with pH.

Abstract- Airlift loop reactors have been used widely for production of diverse bioproducts in chemical and biotechnological industries. Liquid Circulation velocity is a unique design parameter in airlift loop reactor. The principle objective of the present work is to quantify the effect of operational and geometrical parameters on liquid circulation velocity. Experiments were performed to evaluate effect of superficial gas velocity on liquid circulation velocity which was found to increase correspondingly. This can be attributed to increased bubble population which leads to increase in total gas hold up which is driving force for liquid circulation velocity. By decreasing draft tube height, liquid circulation velocity was found to decrease which can be attributed to increase in upper clearance which leds to increased coalescence of bubbles leading to formation of large size bubbles that escape quickly from the system resulting into decreased gas hold up and thus decrease in liquid circulation velocity.
