Climate Conditions

Information Technology is like the central nervous system for business, private sectors, Government organizations and for the social infrastructure. Of course it connects all part of the world. Most of the works are computerized and automated solely depends only on IT. IT sector depends on the electricity to run all the works and at the same time high power consumption emits larger heat by the resources which are threatening and giving unsustainable climatic conditions on the globe. So there is a need to follow the best practices for Energy conservation as well as gradual awareness for bringing environmental sustainability. The best environmental practices can reduce the use of hazardous materials and maximize Energy efficiency during product’s lifetime to avoid Green House Gas Emissions and Co2. Green IT plays a vital role to improve the climate conditions on earth by “Go Green approaches” by effective design, manufacture, use and disposal of e-wastes with no or very minimal cause on the environment. Using Green IT stakeholders or organization can avoid toxic landfills by reduce and reuse equipment’s with the manufacturing of biodegradable components. Through Green IT cost savings is possible with energy efficient products through the best practices, approaches, standards and techniques like virtualization and configuring the servers by power management options and there by gaining energy from renewable natural resources, also switching to digitalization to roll out traditional paper works. In this research paper, the proposed approach is to address the power consumption and environmental issues from various ITC resources like compute, network and storage with better algorithms like ACVFS and Energy-Conscience Workload Scheduling, Resource Efficiency techniques in data centers, thin provisioning and by recycling approaches like 3R’s for managing e-wastes to make the Earth Greener for the next generation.

Due to the advancement of information and communications technology, most of the businesses and services have transformed into an e-businesses and e-services. The organizations are facing a great deal of pressure from regulators to move toward green IT. The aim of this article is to evaluate the factors affecting on green IT readiness from the perspective of IT users, a questionnaire designed for this purpose. The questionnaire divided into two parts, the first part for demographics information, and the second part contains 34 statements divided into 6 factors. There are 460 respondents to the questionnaire. The results of the data analysis showed that the factors, technology and attitude have an agreed degree of agreement, while the practice, policy, governance, and green IT readiness have a neutral degree of agreement. The governance factor has the highest effect on green IT readiness. The article recommends the ministries of electricity must be increasing the awareness for green IT as part of their awareness for power consumption saving.

Since the advent of information technology (IT) is continuously increasing, energy consumption is on the rise, which forces the global world to be directed toward green IT. The Joulemeter program developed by Microsoft used to make the comparisons between computers types. The results showed that laptops consume less power than desktops, and CO2 emissions of the laptop are about 4.5 times less than desktop emission. A questionnaire was developed to evaluate green IT readiness from the perspective of the IT employees. The data collected from 401 IT employees. The results showed the dimension maintenance gain the highest average, which indicates the IT employees realize that the maintenance is an important factor for green IT readiness. The factors, technology, practice, attitude, and maintenance, have an agree degree of agreement; the factors, policy, governance, and green IT readiness, have neutral degree of agreement. The governance has the highest correlation and influence on green IT readiness. The study recommends organizations setup strategies for implementing green IT.

Ubiquitous Network

Power conscious PC processors, mobile processors, cryptography processors, RFID tags, etc. have obviously supported the trend of ubiquitous network and computing. The authors have developed a ubiquitous processor named HCgorilla under the strategy to unify these devices. The unification of those devices has been effective to achieve power consciousnessfor Green IT and secureness for ubiquitous environment. The target of this study is the shift of HCgorilla to SoC, considering the exploitation of adaptability to SoC and resource-constrained implementation is cutting edge microprocessor tendency. Since this requires the total improvement of HCgorilla, the complicated clock schemes are optimally unified together. One of most important clock schemes applied to HCgorilla is a waved MFU (multifunctional unit). Although gated clock and scan path have been supported by standard CAD tools, the wave-pipelining has been mainly done by manual tuning because it has not always been so popular. Thus, these clock schemes are totally introduced. Specific features of the improved HCgorilla and its implementation in a CMOS standard cell chip are described in this article. The HCgorilla.7 chip developed in this study is the best in view of clock speed, occupied area, power consumption, and hardware security.

Increased reliance on technology and online transactions has increased the heat generated in data centres, due to greater access, storage, aggregation and analysis of such data. This paper discusses the downsides of traditional data centres and highlights the importance of applying green IT practices. It explores the benefits and proposes guidelines on shifting to green data centres. The recommendations to go green are to: a) reduce energy by applying green IT practices, b) eliminate redundancies in server systems and cooling modules, c) turn on power management tools on servers and terminals when applicable, d) utilise newer technologies of power consumption and e) minimise internal barriers to establish a good energy management policy. The benefits expected from the proposed approach are minimised pollution levels and lower the cost of activities, among others. The findings of the study will also contribute to face the challenge of global warming and help in better management and control of power consumption. Keywords: Traditional data centres, green data centres, green computing, emission.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
