Abstract: Land use change and ecosystem services value change were studied based on the data of land use survey from 1996 to 2005 in Zhejiang Province. Economic niche, integrated index of land use degree and ecosystem services value were employed. The results show (1)Driving forces of cultivated land conservation in Zhejiang Province increased yearly, land use developed as a whole toward high intensity and extent, but the value of ecosystem services decreased.(2) The ecosystem services value in Zhejiang Province was negatively correlated with economic niche and integrated index of land degree. (3)In the course of urbanization, controlling the extension of construction land, improving the ecological compensation of cultivated land conservation, and reducing economic niche of land use could availably restrain decrease of cultivated land, and advance the growth of 'economy' and 'ecology' harmoniously.

Biotechnology , 2008,
Abstract: The primary goal of technology incubators is to promote the development of technology-based firms while encouraging entrepreneurship among researchers and academics. Biotechnology incubators will help individuals and firms move research from academic laboratories to the marketplace for the benefit of mankind. African governments should provide scientific and business equipment and support services to create an appropriate setting for biotechnology startups. This will establish the continent as a player on the life science frontier and biotechnology innovation.

Abstract: Innovative businesses are often the result of collective action of organisations involved in many-sided market structures, which can be found in and around business incubators or technology centres. Within such frame environments, many group interests beyond those of single producers and their immediate clients exist and interfere. Rather generically, important economic outcomes of innovations are sequences of cost reduction events at the level of economic sectors, where the nature of (sector-wise) technology is influencing the pace of these events. At the conceptual level, we describe the social learning and social innovation process which leads to sustainable innovation by means of the influence exerted by firms on each other within constrained environments such as business incubators. These environments need not to be organized according to any sector logic. We propose that the influence exerted between firms is increasing in firm similarity, in the degree of product complementarity, and also to depend on (mutual) trust relations. We note that, very much in symmetry with the role of sustainability in society as a whole, in the world of firms and markets, the incubation process may be viewed as a moderator, which attempts to overcome the disadvantages of highly paced, short-term oriented capitalist economies. In sections 2 and 3 a concept for representing the societal forces shaping sustainability and incubation for the innovating firm is described and ways of transforming the concept into concrete tools of assessment and valuation are pointed at.
Improving Energy Efficiency of Smart Household Appliances and Devices  [PDF]

Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.24009
Abstract: With the ever-increasing volume of applications of various kinds of electric drives in all spheres of human activity, the issues in improving the efficiency of the electromechanical converters of electric energy, one of the most important components of the electric drive (ED), are becoming increasingly important. Such issues include reducing their weight and size, improving the functional characteristics of these devices to increase their operational life and reducing the cost of manufacture. Taking full advantage of these opportunities relates to the AC and DC single-phase commutator motor (SCM), which is widely used in regulated and high-speed motor drives in home appliances and electric hand tools. The SCM is used in machinery where the load torque has a hyperbolic dependence on the rotational speed and the need to work with a large motor overload due to the “soft” mechanical characteristics of such motors.

Abstract: This article aims to analyze the contribution of Business Incubators for small IT business. In this way, a deep research in three Brazilian IT Incubators was developed. We investigated the perception of incubators’ managers, tenant and graduated entrepreneurs regarding to the key elements of incubation process, as support and infrastructure, university-incubator interaction, and management training. Our findings indicate some deficiencies in IT Incubators, predominantly in prospecting customers, attracting financial resources, and establishing relationships within universities and research centers.
Improving Nitrogen Use Efficiency in Crops for?Sustainable Agriculture  [PDF]

Sustainability , 2011, DOI: 10.3390/su3091452
Abstract: In this review, we present the recent developments and future prospects of improving nitrogen use efficiency (NUE) in crops using various complementary approaches. These include conventional breeding and molecular genetics, in addition to alternative farming techniques based on no-till continuous cover cropping cultures and/or organic nitrogen (N) nutrition. Whatever the mode of N fertilization, an increased knowledge of the mechanisms controlling plant N economy is essential for improving NUE and for reducing excessive input of fertilizers, while maintaining an acceptable yield and sufficient profit margin for the farmers. Using plants grown under agronomic conditions, with different tillage conditions, in pure or associated cultures, at low and high N mineral fertilizer input, or using organic fertilization, it is now possible to develop further whole plant agronomic and physiological studies. These can be combined with gene, protein and metabolite profiling to build up a comprehensive picture depicting the different steps of N uptake, assimilation and recycling to produce either biomass in vegetative organs or proteins in storage organs. We provide a critical overview as to how our understanding of the agro-ecophysiological, physiological and molecular controls of N assimilation in crops, under varying environmental conditions, has been improved. We have used combined approaches, based on agronomic studies, whole plant physiology, quantitative genetics, forward and reverse genetics and the emerging systems biology. Long-term sustainability may require a gradual transition from synthetic N inputs to legume-based crop rotation, including continuous cover cropping systems, where these may be possible in certain areas of the world, depending on climatic conditions. Current knowledge and prospects for future agronomic development and application for breeding crops adapted to lower mineral fertilizer input and to alternative farming techniques are explored, whilst taking into account the constraints of both the current world economic situation and the environment.?
Improving of Efficiency in Data Envelopment Analysis with Interval Data

The International Journal of Applied Economics and Finance , 2010,
Abstract: Aim of this research is study efficiency of Decision Making Units (DMUs) with interval data using Data Envelopment Analysis (DEA) models. The DEA is a widely applied approach for measuring the relative efficiencies of a set of DMUs which uses multiple inputs to produce multiple outputs. An assumption underlying DEA is that all the data are known exactly. But in reality, many factors cannot be measured in a precise manner. In recent years, in different applications of DEA, inputs and outputs have been observed whose values are indefinite. Such data are called imprecise. Imprecise data can be probabilistic, interval, ordinal, qualitative or fuzzy. In this study, we investigate an interval DEA model, in the case that the inputs and outputs are located within the bounded intervals. The resulting model is non-linear and then we convert it to a linear one. Also minimal variations of input and output intervals are computed to achieve to full efficiency. Indeed, we propose a new method for improving of efficiency classifications of DMUs with interval data in data envelopment analysis.

Advances in Fuzzy Systems , 2012, DOI: 10.1155/2012/506082
Abstract: This paper investigates the use of genetic algorithms (GA) in the design and implementation of fuzzy logic controllers (FLC) for incubating egg. What is the best to determine the membership function is the first question that has been tackled. Thus it is important to select the accurate membership functions, but these methods possess one common weakness where conventional FLC use membership function generated by human operators. The membership function selection process is done with trial and error, and it runs step by step which takes too long in solving the problem. This paper develops a system that may help users to determine the membership function of FLC using the GA optimization for the fastest processing in solving the problems. The data collection is based on the simulation results, and the results refer to the transient response specification which is maximum overshoot. From the results presented, we will get a better and exact result; the value of overshot is decreasing from 1.2800 for FLC without GA to 1.0081 with GA (FGA). 1. Introduction Clearly automatic control has played an important role in the advance of engineering and science. In addition to its extreme importance in robotic systems, and at time, automatic control has become an important and integral part of modern manufacturing and industrial processes. Automatic control is essential in such industrial operations as controlling pressure, temperature, humidity, viscosity, and flow in the process industries. While modern control theory [1] has been easy to practice, fuzzy logic controllers (FLC) have been rapidly gaining popularity among practicing engineers. This increase of popularity can be attributed to the fact that fuzzy logic provides a powerful vehicle that allows engineers to incorporate human reasoning in the control algorithm. In our daily life from the production lines in manufacturing plants, medical equipment, and agriculture to the consumer products such as washing machine and air conditioner, FLC can be applied. As for an example, the controller temperature set for incubating egg. Four factors are of major importance in egg incubation artificially: temperature, humidity, ventilation, and turning. Of these factors, temperature is the most critical. If the temperatures are not accurately controlled, the incubated egg will not be uniform. One of the problems with the incubate-egg systems occurs in the design of the temperature controllers. The temperature and relative humidity of incubator should be set at the specific value as proposed by Du et al. [2]. And it is very

Abstract: In order to promote creative industries in Romania, as partners of VIC, we propose an application project related to a personalized guide ofSouth-East Region of Romania as a result of creative firms cooperation. This guide should be a demand of assistance and cooperation with theEuropean partners and must be a signal that Romanian creative firms exist and want to growth up. On the other hand, we try to realize a newframework for virtual incubators in Romania. We have to realize this because there are only information technology incubators in Romania.
