Abstract Parameter sensitivity for large-scale systems that include several components which interface in series is presented. Large-scale systems can be divided into components or sub-systems to avoid excessive calculations in determining their optimum design. Model Coordination Method of Decomposition (MCMD) is one of the most commonly used methods to solve large-scale engineering optimization problems. In the Model Coordination Method of Decomposition, the vector of coordinating variables can be partitioned into two sub-vectors for systems with several components interacting in series. The first sub-vector consists of those variables that are common among all or most of the elements. The other sub-vector consists of those variables that are common between only two components that are in series. This study focuses on a parameter sensitivity analysis for this special case using MCMD.

Discharging of wastes and toxic pollutants produced by the industrial activities into the natural environment which consist of air, water and land implies the term Industrial Pollution. It has serious consequences on human life and its health along with several ways of negative impacts on the environment and nature. As far as our nation is concerned most of the major cities are filled with these large-scale industries which place a crucial role financial development of a country. Strictly hindering the development of industries cannot be done as it is vital for the Socio-Economic progress of a country. Yet it is our duty to protect our natural environment by limiting the pollution due to industries. This Study consist of the issues occurred in Eloor- Kadungalloor region as result of the industrial pollution followed by policies for a development plan to enhance the natural and environmental conditions with a planning approach at micro study level. As far as the Kerala context is considered, the major spot which is mostly affected by the industrial pollution is the ‘Edayar Industrial belt’ which is the largest industrial belt in Kerala. This became one of most noted spot because of the continuous dumping of dangerous chemical pollutants from adjacent industries (pesticide and fertilizer manufacturing). It has also resulted in health issues for the inhabitants of the site. Though many complaints have been filed against the companies, there has no proper laws or schemes for taking measures for reduction of pollution have come up so far. Hence this paper deals with the application of technical solutions and strategies for an Environment Improvement plan development for an industrial as well as studying on the issues of sire and its inhabitants.

As a result of environmental changes, assessment indexes for the agricultural landscape have been changing dramatically. Being at the interface of human activity and the natural environment, hunting is particularly sensitive to environmental changes, such as increasing deforestation or large-scale farming. The classical categorisation of hunting grounds takes into account the area, forest cover, number of forest complexes, fertility of forest habitats, lack of continuity of areas potentially favourable to wild animals. Landscape assessment methods used in architecture often better reflect the actual breeding and hunting value of a given area, especially in relation to fields and forests. The forest-field mosaic, large spatial fragmentation as well as interweaving of natural environment elements with buildings do not have to be the factors that limit the numbers of small game. Identification of the constituents of architectural-landscape interiors: content and significance assessment, determination of the functional role or assessment based on the general environmental values being represented take into account factors important for the existence of game, in particular small game.

This chapter studies the Mughal conquest of the heart of North India. It argues that the heterogeneous geography of this landmass shaped the course and nature of military engagements. The vast open plains of the Punjab and the Gangetic Basin allowed large-scale cavalry manoeuvres. Hence, the Mughals were able to engage their adversaries in a number of battles and skirmishes here. In contrast, the broken terrain of the forested highlands of central India restricted free movement of troops and encouraged fortress warfare. For this reason, Mughal expansion entailed a greater number of sieges here. This environmental heterogeneity also made it impossible for either cavalry or firearms to spearhead Mughal military conquests uniformly or single-handedly. Thus, even within the fairly contiguous region that was to eventually comprise the political heartland of the Mughal empire, the natural environment left a deep imprint on the conduct of warfare and the course of empire-formation.

AbstractCurrent educational discourse holds that effective pedagogy requires engagement through active student participation with subject matter relating to them. The lack of testing of lessons in series is recognized as a potential weakness in the evidence base, not least because standard parallel designs cannot capture serial interaction effects (cf. drug interactions). However, logistic issues make large-scale replicated in situ assessment of serial designs challenging. The recent introduction of evolution into the UK primary school curriculum presents a rare opportunity to overcome this. We implemented a randomised control 2 × 2 design with four inexpensive schemes of work, comparable to drug interaction trials. This involved an initial test phase (N = 1152) with replication (N = 1505), delivered by teachers, after training, in their classrooms with quantitative before-after-retention testing. Utilising the “genetics-first” approach, the schemes comprised four lessons taught in the same order. Lessons 1 (variation) and 3 (deep-time) were invariant. Lesson 2 (selection) was either student-centred or teacher-centred, with subject organism constant, while lesson 4 (homology) was either human-centred or not, with learning mode constant. All four schemes were effective in replicate, even for lower ability students. Unexpectedly, the teacher-focused/non-human centred scheme was the most successful in both test and replicate, in part owing to a replicable interaction effect but also because it enabled engagement. These results highlight the importance of testing lessons in sequence and indicate that there are many routes to effective engagement with no “one-size fits all” solution in education.

Nowadays, absorbing energy from vibration is one of the most promising technologies. In general, the vibrations may be very large, such as the vibrations of tall buildings, large flexible bridges, and ocean platform and so on in some environmental loading. With the global concern on energy and environmental issues, energy absorbing from large-scale vibrations for structural health monitoring purposes is more attractive and becomes a research frontier. A type of damped dynamics vibration energy absorber, where two masses are connected in series with the energy transducer and spring, is built and analyzed in this paper. The relationships among electrical damping ratio, excitation frequency ratio and dimensionless power are analyzed in frequency domain. The optimal parameters for maximizing the power output are discussed in analytical form while taking the parasitic mechanical damping of the system into account. In addition, the numerical simulations in time domain are calculated. The results indicate that when the system is excited by the larger peak of local optimal excitation frequency, more power can be obtained. It is helpful for design of energy absorber device.

The article provides an overview of the causes of the current environmental crisis, with three main sources being identifi ed: industrial development and large-scale agriculture, a rapidly growing global population, and environmental crime.The most serious environmental problems, such as global warming, air and soil pollution have also been characterised. The author briefl y charac-terises the defi nitions related to eco-criminology. The international commu-nity, governments, and NGOs are involved in improving the effectiveness of police cooperation in the fi ght against eco-crime, but it is still not effective enough.Environmental protection is currently one of the most important issues that humanity must address. The quality of our lives and maybe our surviv-al depend on it.

The dynamics of a booster station, which is critical for the control of a novel, long distance, hydraulic capsule pipeline, is simulated mathematically for design studies and control of the hydraulic transients caused by the valve actuators in the system. Several modifications to the pump bypass station configuration of the booster station have been studied. With the objective of eliminating column separation and reducing flow reversals, a configuration with several centrifugal pumps connected in series, and a carefully sized air chamber is found to be a viable design. A valve control method is designed to eliminate column separation and the design results in acceptable flow reversal levels in the main pipe. The simulation results match with trends in limited experimental studies performed on a small scale experimental capsule pipeline system.
