Authors: Leela Krishna K , Umamahesh N V , Srinivasa Prasad A 
Published: October 2019

Abstract
This paper presents a Genetic Algorithm and Non-Linear Programming (GA-NLP) hybrid model to derive steady state optimal reservoir operating policies for a reservoir. In the present study, the objective is maximizing the yields of all the crops in the command area considering yield response to water deficit subject to constraints on reservoir water balance, storage bounds, channel capacities and minimum water requirements. Decision variables of the model are fortnight water allocations to each crop grown under left & right main canals and d/s releases. The model developed is applied to the Nagarjunasagar reservoir in Andhra Pradesh, India. Various levels of dependable inflows entering into the reservoir (75%, 80% & 85%) are considered in the present study. Optimal policy obtained by proposed model are validated through simulation and compared with Standard operating policy (SOP). The results obtained using the proposed model gives guidelines to reservoir managers to take decisions. Results reveal that GA-NLP model can be effectively used for optimal allocation of limited available water resources to any reservoir.

Authors: Phaneendra K , Lalu M 
Published: October 2019

Abstract
In this paper, a quadrature technique is employed for the solution of singularly perturbed delay differential equation. A first-order neutral type delay differential equation is achieved, which is asymptotically equivalent to the given singularly perturbed delay differential equation. Then Gaussian quadrature two-point formula is implemented on the first order equation to get a tridiagonal. Thomas algorithm is used to solve the resulting tri-diagonal system. The proposed method is implemented on model example, for different value of delay parameter and perturbation parameter. Maximum absolute errors are tabulated with a comparison to authorize the method. Theoretical convergence of the method is discussed. The layer behaviour is discussed using the graphical histrionics.

Authors: Charan Kumar G , Varalakshmi M , Tiwari Ankita , Rajyalakshmi K. 
Published: October 2019

Abstract
Taguchi approach is adopted to optimize the process parameters and improve the quality of components that are manufactured. Nature of the output response in any scientific investigation has to be understood through experimentation prior to the development of a suitable mathematical model. When several input variables are involved in the scientific problem, it is very difficult to develop a relation between the output responses in terms of input variables. The objective of this paper is to determine the expected range for the process parameters in the optimization process by introducing fictitious parameter.
Optimal strategy analysis of N-policy Two-Phase M/Ek/1 Vacation Queueing system with Server Start-Up, Time-Out and Breakdown
Authors: Rao A Ankamma , Devi V N Rama , Chandan K 
Published: October 2019

Abstract
This article presents optimalstrategy N-Policy M/Ek/1 vacation queueingsystem when the server is in Start-up, Time-out and Breakdown for two-phase. The individual arrivals considered to follow Poisson process and receive batch service of k-stages in the first phase, individual service in the second phase. During the service arrivals are allowed to enter the batch. On completion of the second phase service to all customers in the second phase, the server come back to the first phaseand do the service to the customers who have arrived by providing them first phase service of k-stages followed by second phase service. If there is no customer waiting in the phase one service, the server waits for a fixed time ‘C’ is called server Time-out. If units arrived during this fixed time, then the server provides first phase followed by second phase service, otherwise after expiration of fixed time he takes a vacation. After N-customers accumulate in the system the server returns from vacation. Before going to first phase service, the server spends a random startup period for pre-service after coming back from vacation. During individual service the server is susceptible to random breakdown according to a Poisson process and the repair time follows an exponential distribution. After repair the server resumes individual service. Exact notations for steady state distribution of the number of customers in the system are derived. Developed a cost model for determining the optimal operating policy at a minimum cost. By using numerical illustrations the sensitivity analysis is also presented.

Authors: Neelima D , Rao V U M 
Published: October 2019

Abstract
Dark energy cosmological models with variable equation of state (EoS) parameter in Brans-Dicke [1] scalar tensor theory of gravitation are obtained. The field equations have been solved by using the anisotropy feature of the universe in Bianchi type-III metric. Some important features of the models, thus obtained, have been discussed. We noticed that as a special case, it is always possible to obtain dark energy cosmological models in general relativity.

Abstract
In this paper we proposed a three species Ecological model with a Prey and Two predators. Distributed type of delay is incorporated in the interaction of prey and second predator is taken for investigation. The system dynamics is studied at its interior equilibrium point with exponential type of delay kernel. The effect of Time delay on the dynamical behavior of the system is studied using Numerical simulation. It is shown that the delay arguments with different weight parameters exhibit rich dynamics and the system is asymptotically stable.

Abstract
In this paper we have investigated the non-static plane symmetric model in the presence of dark energy and one dimensional cosmic string in the frame work of Barber’s second self creation theory by using hybrid scale factor. We have discussed some physical and geometrical properties of the obtained model such as spatial volume(V ), deceleration parameter (q), expansion scalar(θ), Hubble parameter (H), shear scalar (σ), anisotropic parameter (Ah

Published: October 2019

Abstract
The present work deals with a spatially homogeneous and anisotropic Kantowski-Sachs space-time filled with bulk viscous fluid, containing one-dimensional cosmic strings. To obtain a deterministic solution of the field equations, we used the assumption of shear scalar is proportional to expansion scalar of the model. We have investigated geometric and kinematic properties of our bulk viscous string model and discussed the role of bulk viscosity in the evolution of Kantowski-Sachs universe within the framework of f(R) modified theory gravity. A detailed physical discussion of the dynamical parameters is presented through a graphical representation.

Analysing electricity demand in neighbourhoods with electricity generation from solar power systems: A case study of a large housing cooperative in Norway
Authors: Sørensen Åse Lekang , Sartori Igor , Lindberg Karen Byskov , Andresen Inger 
Published: October 2019

Abstract
An energy management system can be introduced on a neighbourhood level, to achieve energy goals such as increased self-consumption of locally produced energy. In this case-study, electricity generation from photovoltaic (PV) systems is simulated at Risvollan housing cooperative, a large housing cooperative in Norway. The electricity generation from PV systems of different orientations and capacities are analysed with the electricity load. Key performance indicators (KPIs) such as self-generation, self-consumption and generation multiple are described, based on hourly values. The electricity generation from the south-oriented building façade PV systems are about 5-6% higher than for the east-west oriented rooftop PV systems on an annual basis, since the façade PV systems generate more electricity in the spring and autumn. The self-consumption factor is the most important KPI in Norway, due to the national tariff structure. For the total housing cooperative, a PV capacity of about 1,000 kWp seem suitable, giving a self-consumption factor of 97% for a rooftop system, based on 2018 electricity and climate data. From the perspective of the housing cooperative, it is financial beneficial to aggregate electricity loads for common areas and apartments, since a higher share of the electricity can be used by the cooperative. For this to be possible, also housing cooperatives with PV must be facilitated for in the prosumer agreement. Comparing a single 1,100 kWp PV system providing electricity to the total cooperative with 22 PV systems of 50 kWp behind 22 garage meters, the self-consumption factor decreases from 95% to average 14%, resulting in a 41% lower financial value for the PV electricity.

Authors: Lund K M , Lausselet C , Brattebø H 
Published: October 2019

Abstract
Buildings represent a critical piece of a low-carbon future and their long lifetime necessitates urgent adoption of state-of-the-art performance standards. So far, LCA studies have assessed buildings, mobility and energy systems mainly individually. Zero Emission Neighbourhoods (ZEN) give a unique chance to combine these elements. In Norway, the Research Centre on ZEN has as a goal to enable the transition to a low carbon society by developing sustainable ZENs.
In this study, a LCA model for neighbourhood based on a modular structure with five physical elements; buildings, mobility, infrastructure, networks and on-site energy was applied on Ydalir, a pilot project of the ZEN Centre. Revealing that regardless of which scenario considered, the ZEN Ydalir does not achieve their ambitious goal of zero emissions. Further, the results show that the operation of mobility is a major source of the total greenhouse gas (GHG) emissions, accounting for 21-46%. Considering the life cycle stage materials, buildings are the largest contributor representing 24% of all GHG emissions. Thus, these two areas have been highlighted as the best options for improvement. Parameters related to uncertainties or are large contributors to the environmental impact are included in a sensitivity analysis.

Published: October 2019

Abstract
Climate responsive urban design that makes use of passive heating and cooling strategies and enhances pedestrian comfort is a key element to a sustainable society. Knowing the impact of different materials, building typologies and arrangements and a building’s sensitivity to microclimatic conditions, the energy balance can be enhanced. This study aims to evaluate the microclimatic conditions at the campus of the Norwegian University of Science and Technology, located in Trondheim, Norway. A numerical model was used and validated with punctual measurements on site. The results for air temperature showed a considerable seasonal variation with highest spatial temperature differences in summer and lowest in winter. Regarding the analysis of the wind field, east-west passages were identified as problematic. The influence of the seasonal changing leaf area density of the vegetation had a visible but minor influence on the wind field. The calibrated model will be used for further research on the influence of new building bodies on microclimate and thus building energy demand and pedestrian comfort.
Comparison of different measures for reducing the carbon footprint of the building sector – a rental house case study
Authors: Holopainen R , Ahola R , Bergbom K , Vaarala H 
Published: October 2019

Abstract
This paper compares and estimates cost-optimal means to increase the potential of reducing the carbon footprint of future rental houses. As a case study we present a comparison between four rental apartment houses, where one house has achieved the Nordic Swan ecolabel. The carbon footprints of these buildings have been calculated for the building lifetime. According to the results, the effects of single measures are quite small in reducing the carbon footprint, but larger effects can be obtained by combining several measures together. It is essential to minimize the amount of used materials by paying attention to material efficiency under both design and construction phase. The paper also discusses the role of the voluntary ecolabelling of buildings as a tool to reduce the carbon footprint of the building sector.

Published: October 2019

Abstract
Green Bonds are an instrument for driving the environmentally friendly and low-carbon economy. Green Bonds are bonds whose proceeds are earmarked for and transparently channelled to environmentally-friendly projects and activities. The real estate industry has a multi-decade track record of addressing environmental impacts through the use of rating systems certified by independent third parties. Green building certification systems address multiple environmental impacts and measure outcomes across all asset lifecycle phases. Using bonds for such investments is not new but in an effort to improve transparency and increase opportunities both for issuers and investors it can take a more active role in combating climate change. The goal of this paper is to describe how property developer can use Green Bond as one instrument in sustainable life cycle management and continuous development of properties. The method used is a case study of Finnish property owner company, which commits to invest the funds raised in certified, environmentally responsible and energy-efficient projects. The single case study method employed in this study captured the process of case organization towards Green Bond initiative. More precisely the data was gathered by qualitative document analysis (QDA). The results show that company begin the process with focusing on environmental sustainability especially putting the effort in the first phase to energy efficiency. The Green Bond initiative provided a new avenue towards economic sustainability. Additionally, issues like shared use of facilities was discussed from social sustainability perspective. The results are interesting for property owners who are interested in systematic development towards regenerative built environment.
Energy analysis and energy planning for kindergartens based on data analysis
Authors: Ding Yiyu , Brattebø Helge , Nord Natasa 
Published: October 2019

AbstractThe aim of the study was to utilize different building data for prediction of development in energy use of a typical building type. In this study, energy use and its future development for kindergartens in Trondheim, Norway, were analyzed. The energy use data were retrieved from the energy monitoring platform of Trondheim Municipality. The total area of all the kindergartens was about 76 000 m2, where the area of each kindergarten was ranging from 100 – 4 471 m2. Firstly, typical heat and electricity duration curves per m2of kindergartens in Trondheim within six years were identified. Secondly, the kindergartens were divided into two cohorts based on their connection to district heating (DH). The average total annual energy use was 177 kWh/m2for kindergartens without DH, and 168 kWh/m2for kindergartens connected to DH. The peak load values were similar for both cohorts, about 140 W/m2. Analysis of the duration curves showed a bigger electricity load variation for the kindergartens without DH connection. Within the building cohort with DH, three cases were found depending on the energy share from DH; i.e. DH high share, DH average share, and DH low share. By following different background data for CO2factors of electricity and local DH, the kindergarten with DH high share had almost the lowest annual CO2emission. Contrarily, the annual CO2emission of a kindergarten with lower share of DH, or without DH, usually had a wider range of emissions due to its dependence of the electricity production mix. Finally, a prediction was made by assuming 14.2 % growth rate of kindergartens on the ground of the average six-year total kindergarten area. The result showed that if more than 50-67 % of the new building area would be connected to DH, a smaller increase of CO2emission from the projected area could be achieved, depending on the relevant CO2factors. This proved that buildings with DH were more robust than the one without DH concerning CO2emission. The suggested analysis method and identified duration curves could be used to as a reference example for defining energy profiles of other building types. These profiles are necessary for diversifying and upgrading local energy supply pathways, infrastructure sizing, and improving urban energy planning.
