Title: Performance Analysis of Mobile Nodes in Mobile Ad-hoc Networks using Enhanced Manhattan Mobility Model Authors: Kour, S; Ubhi, J Singh Abstract: The fundamental characteristics of Mobile Ad-hoc Networks differentiation from other wireless or wired networks are mobility and scalability. We are proposing a new method of speed calculation of mobile nodes in this paper. MANET routing protocols are designed to handle changes in physical arrangements of mobile nodes along with minimizing packet overhead, and packet loss rate. This paper checks the performance of AODV, DSDV, and DSR routing protocols under Enhanced Manhattan Mobility Model. For better movement of mobile nodes and network performance, node mobility is considered. Firstly, we propose an Enhanced Manhattan Mobility Model. The simulative study compared the proposed mobility model over existing mobility model using the NS2.35 simulator and Bonnmotion-3.0.1 mobility generator tool. Analysis shows that the simulated results presented in this paper have shown enhancement of Quality of Service performance metrics like packet overhead, and packet loss. It shows an improvement of 0.7% to 21% in packet overhead and drops rate of 1% to 7% in packet loss. Page(s): 69-72

Title: Research on the Factors Influencing Overcapacity in Industrial Sectors Authors: Feng, Mei; Yan, Yafen Abstract: Industrial overcapacity is caused by a combination of many factors. This paper selects the relevant indicators which have a great influence on overcapacity from the aspects of government, industry, and enterprises. The study builds a tobit model, quantitatively analyzes the factors influencing of the overcapacity in China's industrial sectors, and puts forward relevant policy suggestions to resolve this overcapacity.

Determinants of Environmental Innovations: New Evidence at the sector Level

2019-02-01T00:00:00Z

Title: Determinants of Environmental Innovations: New Evidence at the sector Level Authors: García-Pozo, Alejandro; Campos-Soria, Juan A; Santos, Margarida Custódio; Santos, José António C Abstract: This study carried out an empirical analysis of environmental innovations based on firm-level data from the Technological Innovation Panel (i.e. PITEC) 2014 database created by the Spanish Institute of Statistics. The main goal was to explore the determinants of eco-innovation in the primary, secondary, and tertiary sectors. The methodology applied revealed that, although most of the proposed model’s determinants are significant for all sectors, the determinants’ effects are specific to each sector. Improvements of products and processes, organisational innovations, research and development, and public financial support for innovation activities are the main drivers for eco-innovation in all sectors. However, these determinants’ effects significantly vary across sectors. This study’s main conclusion is that international competition is quite important for eco-innovation and economic aid programmes are essential to the implementation of eco-innovation measures.

Title: Statistical Modeling of β-Galactosidase Production from Novel Yeast Isolate Using Cheese Whey Authors: Kumari, S; Panesar, P S; Kaur, R; Bera, M B Abstract: Whey, a liquid component remaining after milk fat and casein have been separated from whole milk, is one of the major disposal problems of the dairy industries. To overcome this problem, biotechnologically a better alternative is subjecting the whey to processes through which the value added products can be formed. In the present investigation, Response Surface Methodology (RSM) was applied to optimize the different process parameters for β-galactosidase production from whey based medium using novel yeast isolate. The concentration of yeast extract, urea, pH, incubation time and temperature has shown significant effect on the production of the β-galactosidase. The maximum enzyme activity of 1.73 IU/ mg dry weight was observed under the optimized fermentation conditions. Thus, the processing of whey into useful products not only results in reduction of environmental pollution but also helps in the preparation of valuable products in a very cost effective manner.
