Life Cycle Energy Analysis of a Multifamily Residential House: A Case Study in Indian Context  [PDF]
Talakonukula Ramesh, Ravi Prakash, Karunesh Kumar Shukla
Open Journal of Energy Efficiency (OJEE) , 2013, DOI: 10.4236/ojee.2013.21006
Abstract: The paper presents life cycle energy analysis of a multifamily residential house situated in Allahabad (U.P), India. The study covers energy for construction, operation, maintenance and demolition phases of the building. The selected building is a 4-storey concrete structured multifamily residential house comprising 44 apartments with usable floor area of 2960 m2. The material used for the building structure is steel reinforced concrete and envelope is made up of burnt clay brick masonry. Embodied energy of the building is calculated based on the embodied energy coefficients of building materials applicable in Indian context. Operating energy of the building is estimated using e-Quest energy simulation software. Results show that operating energy (89%) of the building is the largest contributor to life cycle energy of the building, followed by embodied energy (11%). Steel, cement and bricks are most significant materials in terms of contribution to the initial embodied energy profile. The life cycle energy intensity of the building is found to be 75 GJ/m2 and energy index 288 kWh/m2 years (primary). Use of aerated concrete blocks in the construction of walls and for covering roof has been examined as energy saving strategy and it is found that total life cycle energy demand of the building reduces by 9.7%. In addition, building integrated photo voltaic (PV) panels are found most promising for reduction (37%) in life cycle energy (primary) use of the building.
Life Cycle Energy of Low Rise Residential Buildings in Indian Context  [PDF]
Talakonukula Ramesh, Ravi Prakash, Karunesh Kumar Shukla
Open Journal of Energy Efficiency (OJEE) , 2014, DOI: 10.4236/ojee.2014.34012
Abstract: Life cycle energy of the building accounts for all energy inputs to the buildings during their intended service life. Buildings need to be constructed in such a way that energy consumption in their life cycle is minimal. Life Cycle Energy (LCE) consumption data of buildings is not available in public domain which is essentially required for building designers and policy makers to formulate strategies for reduction in LCE of buildings. The paper presents LCE of twenty (20) low rise residential buildings in Indian context. LCE of the studied buildings is varying from 160 - 380 kWh/m2 year (Primary). Based on the LCE data of studied buildings, an equation is proposed to readily reckon LCE of a new building.
Energy and Emission Reduction Potential for Bank ATM Units in India  [PDF]
Hemant Kumar Singh, Ravi Prakash, Karunesh Kumar Shukla
Open Journal of Energy Efficiency (OJEE) , 2016, DOI: 10.4236/ojee.2016.54010
Abstract: With the growing economy of India, banking sector growth has led to installation of thousands of Automatic Teller Machines (ATMs) throughout the country. ATMs provide 24 × 7 services as well as operate at low-temperature ranges of cooling, hence have high operating energy costs. Insulating an ATM’s envelope is not a prevalent technique in India. In the present study, an effort has been made to determine the optimum insulation thickness for three different insulation materials for the typical ATM envelope in four different climatic zones of India. Life cycle savings and payback periods for various insulation materials are also evaluated. Further, these optimally insulated ATM envelopes can be integrated with grid connected rooftop solar PV systems. The energy saving and emissions reduction potential due to these two interventions have been estimated on the national basis. Altogether in the four selected climate zones, energy saving of 17% - 30% provides the annual economic benefit of Indian National Rupees (Rs.) 3570 million with annual carbon reduction potential of about 0.60 million tCO2. From this study, it is observed that properly insulated ATMs integrated with rooftop solar PV systems, can significantly reduce the energy costs as well as carbon emissions in India’s context.

Design of a Li-Fi Transceiver  [PDF]
Pavas Goswami, Manoj Kumar Shukla
Wireless Engineering and Technology (WET) , 2017, DOI: 10.4236/wet.2017.84006
Abstract: The latest uproar in this era is about a technology termed as Light Fidelity or more commonly known as Li-Fi. There are currently two trends being seen: First, the extension or enrichment of wireless services and other being increased in user demand for these services, but the available RF spectrum for usage is very limited. So the new technology of Li-Fi came into picture, which uses visible light as a source of communication. Li-Fi is the most recent development which is resourceful. In this technology, LEDs are used to transmit data in the visible light spectrum. This technology can be compared with that of Wi-Fi and offers advantages like increased accessible spectrum, efficiency, security, low latency and much higher speed. This research paper aims at designing a Li-Fi transceiver using Arduino that is able to transmit digital data. The hardware has been designed using Eagle CAD (version 7.1.0) tool and Proteus design tool (version 8). The software coding is done by using Java (version 8). Successful transmission and reception of text, image and video signals is carried out on the transceiver. Hence this research work gives an innovative way of designing a transceiver which works by using off the shelf low cost components and using visible light spectrum.

Thermal Characterization of Se80-xTe20Inx Glasses Using Iso-Conversional Methods  [PDF]
Renu Shukla, Pragya Agarwal, Ashok Kumar
Journal of Crystallization Process and Technology (JCPT) , 2012, DOI: 10.4236/jcpt.2012.22009
Abstract: Alloys of Se80-xTe20Inx glassy system are obtained by quenching technique and crystallization kinetics has been studied using Differential Scanning Calorimetric [DSC] technique. Well defined endothermic and exothermic peaks are ob- served at glass transition temperature (Tg) and crystallization temperature (Tc). From DSC scans, Tc is obtained at dif- ferent heating rates (5, 10, 15, 20, 25 K/min). It is observed that Tc increases with increasing heating rate for a particular glassy alloy. Activation energy of crystallization (Ec) has been calculated by different Non-isothermal Iso-conversional methods, i.e., Kissinger-Akahira-Sunose [KAS], Friedman, Flynn-wall-Ozawa [FWO], Friedman-Ozawa [FO] and Sta-rink methods. It is observed that Ec is dependent on extent of crystallization (α). Activation energy is also found to vary with atomic percentage of In in ternary Se80-xTe20Inx glassy system. The compositional dependence of Ec shows a re-versal in the trend at x = 15 in Se80-xTe20Inx, which is explained in terms of mechanically stabilized structure at this composition.

Chaitra Srinivas, Ajit Kumar Reddy, Anil Kumar Shukla, Himabindhu Pinnammaneni
Open Journal of Medical Imaging (OJMI) , 2016, DOI: 10.4236/ojmi.2016.61002
Abstract: Gluteal hernias are extremely uncommon and occur as a result of deficiency or defect in the gluteal musculature. Our case reports one such incidence in a one year old girl with review of available literature. The clinical presentation and imaging findings are discussed comprehensively. We thus lay emphasis on the importance of real-time ultrasonography as the method of choice to identify hernia contents, peristalsis and obstruction if any.
An Approach for Design of Noise Barriers on Flyovers in Urban Areas in India
Arvind Kumar Shukla
International Journal for Traffic and Transport Engineering , 2011,
Abstract: Transport is a significant, often major source of environmental pollution consisting of noise and air. Noise pollution has become a major concern for communities living in the vicinity of urban roads and major highway corridors. In view of increasing noise levels along highways it has become essential to reduce the intensity of noise to acceptable limit by constructing noise barrier. To study the existing noise levels in the urban areas due to movement of vehicles, the entire city of Lucknow has been divided in different zones on the basis of different land use. Effect of other factors like type of terrain, speed of traffic, cross section of roads and traffic composition has also been considered during noise data analysis. In this paper noise levels on the fly over in front of Engineering College (IET Lucknow UP India) has been taken for study and a noise barrier for this location has been designed for predicted noise levels worked out using modified FHWA model. This model makes use of traffic data like volume, speed composition, slope, ground cover etc. A program in EXCEL was developed to work out barrier height using traffic and road geometry data. The height of noise barrier to reduce the noise level from 63.79 db to 55 db was found as 4.2 meters above the floor level of flyover.
