Comparison of overdeepened structures in formerly glaciated areas of the northern Alpine foreland and northern central Europe
Authors: Gegg Lukas , Preusser Frank
Published: January 2023

Abstract. Overdeepened structures occur in formerly and presently glaciated regions around the earth and are usually referred to as overdeepenings or tunnel valleys. The existence of such troughs has been known for more than a century, and they have been attributed to similar formation processes where subglacial meltwater plays a decisive role. This comparison highlights that (foreland) overdeepenings and tunnel valleys further occur in similar dimensions and share many characteristics such as gently sinuous shapes in plan view, undulating long profiles with terminal adverse slopes, and varying cross-sectional morphologies. The best explored examples of overdeepened structures are situated in and around the European Alps and in the central European lowlands. Especially in the vicinity of the Alps, some individual troughs are well explored, allowing for a reconstruction of their infill history, whereas only a few detailed studies, notably such involving long drill core records, have been presented from northern central Europe. We suggest that more such studies could significantly further our understanding of subglacial erosion processes and the regional glaciation histories and aim to promote more intense exchange and discussion between the respective scientific communities.

Abstract. Cumulus clouds are common over maritime regions. They are important regulators of the global radiative energy budget and global hydrologic cycle, and a key contributor to the uncertainty in anthropogenic climate change projections due to uncertainty in aerosol-cloud interactions. These interactions are regionally specific owing to their strong influences on aerosol sources and meteorology. Here, our analysis focuses on the statistical properties of marine boundary layer (MBL) aerosol chemistry and the relationships of MBL aerosol to cumulus cloud properties just above cloud base as sampled in 2019 during the NASA Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex). The aerosol and clouds were sampled by instruments on the NASA P-3 aircraft over three distinct maritime regions around the Philippines: the West Pacific, the South China Sea, and the Sulu Sea. Our analysis show three primary sources influenced the aerosol chemical composition: marine (ocean source), industrial (Southeast Asia, Manila, and cargo and tanker ship emissions), and biomass burning (Borneo and Indonesia). The marine aerosol chemical composition had low values of all sampled chemical signatures, specifically median values of 2.3 µg/m3 of organics (ORG), 6.1 µg/m3 of SO4, 0.1 µg/m3 of NO3, 1.4 µg/m3 of NH4, 0.04 µg/m3 of Cl, and 0.0074 µg/m3 of refractory black carbon (BC). Chemical signatures of the other two aerosol source regions were: industrial, with elevated SO4 having a median value of 6.1 µg/m3 and biomass burning, with elevated median concentrations of ORG 21.2 µg/m3 and BC 0.1351 µg/m3. The industrial component was primarily from ship emissions based on chemical signatures. The ship emissions were sampled within 60 km of ships and within projected ship plumes. Normalized cloud-droplet size distributions in clouds sampled near the MBL passes of the P-3 showed that clouds impacted by industrial and biomass burning contained higher concentrations of cloud droplets, by as much as 1.5 orders of magnitude for sizes with diameters < 13 µm compared to marine clouds, while at size ranges between 13.0–34.5 µm the median concentrations of cloud droplets in all aerosol categories were nearly an order of magnitude less than the marine category. In the droplet size bins centered at diameters > 34.5 µm concentrations were equal to, or slightly exceeded, the concentrations of the marine clouds. These analyses show that anthropogenic aerosol generated from industrial and biomass burning sources significantly influence cloud base microphysical structure in the Philippine region enhancing the small droplet concentration and reducing the concentration of mid-sized droplets.
Atmospheric drivers of melt-related ice speed-up events on the Russell Glacier in Southwest Greenland
Authors: Schmid Timo , Radić Valentina , Tedstone Andrew , Lea James M. , Brough Stephen , Hermann Mauro
Published: January 2023

Abstract. The Greenland ice sheet is a major contributor to current and projected sea level rise in the warming climate. However, uncertainties in Greenland’s contribution to future sea level rise remain, partly due to challenges in constraining the role of ice dynamics. One process that has the potential to indirectly affect the mass budget of the ice sheet are transient ice accelerations, or ice speed-up events, lasting from one day to a week and triggered by overloading the subglacial drainage system with an increase in water supply. In this study, we identify melt-induced ice speed-up events at the Russell Glacier, Southwest Greenland, in order to analyse synoptic patterns driving these events. The short-term speed-up events are identified from daily ice velocity time series collected from six GPS stations along the glacier, for each summer (May–September) from 2009 to 2012. In total, 45 ice speed-up events are identified, of which 36 are considered melt-induced events where melt is derived from two in-situ observational datasets and one regional climate model forced by ERA5 reanalysis. 16 out of the 45 speed-up events co-occur with lake drainage events, and only four are linked with extreme rainfall events. The 36 melt-induced speed-up events occur during synoptic patterns that can be grouped into three main clusters: (1) patterns that resemble atmospheric rivers with a landfall in Southwest Greenland, (2) patterns with anticyclonic blockings centred over Southwest Greenland, and (3) patterns that show low pressure systems centred either south or southeast of Greenland. Out of these clusters, the one resembling atmospheric river patterns is linked to the strongest speed-up events induced by a 2–3 day continuously increasing surface melt driven by anomalously high sensible heat flux and incoming longwave radiation. In the other two clusters, the net shortwave radiation dominates the contribution to the melt energy. As the frequency and intensity of these weather patterns may change in the warming climate, so may the frequency and intensity of ice speed-up events, ultimately altering the mass loss of the ice sheet.

Reflection of lament in literature
Authors: Anand Neha
Published: January 2023

It is righty said that “Literature is a mirror of life.”Literature is a mode of expression of feelings and emotions. All the ills, customs, rituals, sacraments even the human emotions are beautifully expressed in literature and so are the case with lament also. Lament is simply a song or poem expressing deep grief or mourning. It is such a strong feeling that nothing and no one in the world can give relief from lament. Many of the oldest and most lasting poems in human history have been laments. Even Lament is there in Hindu Vedas and in ancient Near Eastern religious texts, including the Mesopotamian city laments such as Laments for Ur and the Jewish Tanakh. As long as human beings do have emotions feelings, literature will be created and will be read. Through this paper I would like to discuss lament which is present in different works of different poets and authors.

For the last several billion years, nature has nurtured the planet evolving complex Eco-systems that conserve and recycle energy and materials. Climate change is the most visible result – storms, droughts, floods and the like are rising in frequency and severity and the consensus is that we are to be blamed. Civil constructions in urban areas are essential for overall development and benefits of the community, but, it is more important that every such activity be environment friendly as the Environment too has a right to remain protected from any kind of damages. We are, however, the agents of our own eventual doom. We are gradually choking and poisoning ourselves.
This paper covers the attempt in sustainable designing and construction of series of flyovers, Underpasses, River Bridges and other infrastructure projects taken up in the new millennium in New Delhi, the capital city of India. The successful efforts in achieving sustainability are discussed specifically in case of Mukarba Chowk Grade Separator and Barapulla Elevated Road projects.
To assess the amount of the degradation and attempt for sustainable construction, it is essential to understand the environmental characteristics of the area in which structure is taking birth. Once a sincere assessment is done, then it is the core part of ethics of any Engineering to mitigate the degradation and achieve sustainability.
Comparison and Contrast: Shelley and Keats and their Nature Poetry
Authors: Sharma Deepika
Published: January 2023

Though P. B. Shelley and John Keats were mutual friends and were very much similar in thoughts, imagination, creation and also in their lifetime but they have possessed somewhat opposite qualities in their creativity. Keats is the poet of senses, and he loves Nature because of her sensual appeal, her appeal to the sense of sight, the sense of hearing, the sense of smell, the sense of touch. He was not much attracted by the mysteries in nature but rather found reposeful and concrete beauty in nature. He wanted to leave the world of sorrow and escape into the world of imperishable beauty where his nightingale sings. He treats nature as an observer, as a traveler. He finds interest to appreciate the physical beauty of Nature. P.B. Shelley tends to invoke nature as a sort of supreme metaphor for beauty, creativity, and expression. He treats the natural objects as the supreme elements of inspiring him. This paper attempts at a comparative study of Shelley and Keats and their Nature Poetry.

Published: January 2023

Manufacturing of composite is one of the prominent and economical routes for development and processing of metal matrix composite materials. Composite is a multiphase material that exhibits a significant proportion of the properties of both constituting phase such that a better combination of properties is realized. The composite industry has begun to recognize that the commercial application of composites promise to offer much larger business opportunities than the aerospace sector due to the sheer size of transportation industry. A vast majority of the scientist reported that production of composites using mechanical properties as tensile strength, hardness, impact strength more uniform distribution of reinforced particle, metal matrix composite poses some attractive properties when compared with organic matrices. These include strength retention at higher temperature, higher transverse strength, batter thermal conductivity, higher erosion resistance. Buckling behavior of such materials are the keen area of research due to the instability of various materials subjected under variable loads and dynamic conditions. This article is a survey of literature on composite materials regarding their fabrication and characterization and its buckling behavior analysis.

Purpose of this study is to check the effect of opening of the organized retail stores on the economic conditions in terms of job opportunities, income and purchasing power of farmers of Haryana and Himachal Pradesh. The scope of the study is only those farmers who are linked with Mother Dairy, Reliance Fresh and Walmart. The data has been collected through the help of a questioner filled from farmers and analyzed by applying one way ANOVA. It has been found that farmers have different opinion regarding positive effect of retail companies on farmer‟s income, job opportunities, purchasing power and timely payments to the farmers on the basis of the procurement area. The income effect has been found more in case of Reliance Fresh, favoritism is more in Walmart, purchasing power has increased of Walmart and Reliance Fresh linked farmers. One of the finding is that as the people are becoming older and older their perception towards retail companies is keep on changing. Further, it is concluded that as the education level of the farmers increases they become more cautious. The marginal and relatively small farmers believe that their income has increase after linked with retail companies. Retail companies do not favour large sized farmers over small farmers. Most of the farmers accept that payments are made in time and job opportunities for rural people may increase. During visit I observed that most of the labours and employees of retail companies are of other states.

Published: January 2023

Many people feel that solid waste management is simply putting waste into a vehicle and unloading it at a dump. But if we consider it true then why do so many towns suffer from uncollected refuse, blocking street and drains, harbouring flies and rats and degrading urban environments? Successful solid waste management is rarely achieved without thought, efforts and much learning from mistakes. Preparation and management of a good solid waste management system needs inputs from a range of disciplines, and careful consideration of local conditions.
Keeping in mind all above, the present paper is an attempt to combine several aspects of environmental, biological, chemical and civil engineering to resolve the problem related to solid waste management for the Moradabad district. It is felt that there is need to focus more on recycling and resource recovery as a common practice, need to focus on environmental impacts (e.g. surface and groundwater) of solid waste around dump sites etc a plan was prepared for its proper management. At present A2Z Waste Management Private Limited is involving for the solid waste management work in Moradabad. Data related to waste generation, composition of municipal solid waste etc is provided by Nagar Nigam, Moradabad, Municipal Corporation and A2Z Moradabad.

Published: January 2023

Dividend policy has been an issue of interest in financial literature since Joint Stock Companies came into existence. Dividends are commonly defined as the distribution of earnings (past or present) in real assets among the shareholders of the firm in proportion to their ownership. . Dividends are usually given as cash (cash dividend), but they can also take the form of stock (stock dividend) or other property. Dividend payment affects a significant impact on wealth of shareholders of accompanies. However, some theories such as the Miller-Modigliani hypothesis theory say thatdividend has no relevance on value of firms. On the other hand Walter and Gordon propagated a theorywhich supposed that investment policy and dividend policy of a company are interlinked andsignificantly affects price of its shares. This descriptive research proposes to test the Walter and Gordontheory by analysing the impact exerted by dividend policy made by companies on prices oftheir shares. The study is based on secondary data, pertaining to share prices of companies indexed inBombay Stock Exchange (BSE), which have made dividend policy. For the result of the study researcher analysed the data by using the Statistical package of SPSS, employing the statistical tool of T Test Analysis. Resultsof the study reveal that a dividend policy exerts a significant impact on share prices ofcompanies.

Published: January 2023

A Wireless Sensor Network (WSN) is composed of sensor nodes spread over the field to sense the data. The sensed data must be gathered transmitted to Base Station (BS) for end user queries. Sensor nodes can be deployed in the harsh environment. As we know that Energy efficient routing is one of the key issues in wireless sensor network because all the nodes are battery powered, so failure of one node affects the entire network that’s why Energy saving is always crucial to the lifetime of a wireless sensor network. Many routing protocols have been proposed to maximize the network lifetime and decrease the energy consumption. But these algorithms do not define how to collect data quickly in efficient way. We proposed an algorithm to provide this service. The main purpose of the proposed algorithm is to reducing the time in the collection process of data in the wireless sensor networks.

This paper mainly focuses on CFCs and their alternatives to their use. The main critical issue in the field of green technologies is to develop the relationship between ODP and GWP and suggest new and alternative refrigerants which do not damage ozone layer and not to increase global warming. The first and second law thermodynamic analysis of vapor refrigeration system of 1.5 ton capacity for seven eco-friendly refrigerants such as ( R-134a, R-404a, R-407C, R-502, propane(R-290), isobutene(R-600a), butane (R-600)) have been carried out in terms of performance parameters such as COP, EDR, Exegetic efficiency, ratio of exergy destruction in components such as condenser, compressor, throttle valve and evaporator. These performance parameters have been evaluated by varying condenser temperatures in the range from 303 K to 333K and evaporator temperatures in the range from 253 K to 278K. It was observed that R-290 and R-600 (butane) and R-600a (isobutene) of zero ODP and zero GWP is best alternatives if its flammable problem will mitigate and R-134a (of zero ODP and 1300 GWP), R-407c, R-404a and R-410a are the next option of R-22 refrigerant but it needs larger size of compressors which increases the cost of the system.

Published: January 2023

While cremation is an established Hindu ritual practice since ancient times and the Hindu religion permits the cremation of dead body in day-time only, there is much more scope of solar crematorium in this ritual; as solar power is also available in day-time only. Between 500 and 600 kg of wood are used to cremate a dead body. Many trees are felled to meet this requirement. As a result we are significantly contributing in global warming and polluting the atmospheric air much more. Therefore today, world is moving towards the sustainable energy sources which are renewable and biodegradable in nature. One of most sustainable energy source is sunlight that too is inexhaustible and available free of cost. The heat (energy) produced is very clean with no pollutants. So above environmental problems can be the addressed very well by using solar crematorium. Therefore anyone can be a firm believer of world powered by solar energy. In this paper, a special concentrator has been designed to supply required sufficient heat energy to the crematorium by concentrating solar energy. Its speciality is a flexible surface curvature and simultaneously with a non-moving focal area.

Authors: M. S. Ranganath , . Vipin , Maurya Sudhanshu , Yadav Sonu
Published: January 2023

Neural Networks are information processing systems and can be used in several areas of engineering applications and eliminate limitations of the classical approaches by extracting the desired information using the input data. The advantage of the usage of neural networks for prediction is that they are able to learn from examples only and that after their learning is finished, they are able to catch hidden and strongly nonlinear dependencies, even when there is significant noise in the training set. One of the most specified customer requirements in a machining process is surface roughness. For efficient use of machine tools, optimum cutting parameters are required. Therefore it is necessary to find a suitable optimization method which can find optimum values of cutting parameters for minimizing surface roughness. The turning process parameter optimization is highly constrained and nonlinear. Many researchers have used an artificial neural network (ANN) model for the data obtained through experiments to predict the surface roughness. The results obtained, conclude that ANN is reliable and accurate for solving the cutting parameter optimization. The paper work presents on all studies where ANN has been used to analyse surface roughness in turning process.

This paper represents the model which shows the temperature distribution of inductively heated copper cylinder after 10 hours with active cooling by making the coil conductors hollow shape with circulating water flow inside. It was observed that for modest flow rates, the coolant flow becomes highly turbulent which makes the heat transfer between conductor and fluid very efficient. This model illustrates a simplified way of modeling water cooling based on the assumption of turbulent flow and instantaneous mixing. For mechanical support and electrical insulation, the cylinder and coil are embedded in FR4 composite material. The current in the coil has amplitude of 2kA while the average temperature of copper cylinder has increased from 293 K to 346 K. Using this model the temperature evolution in the center of the copper cylinder and in the cooling channel is also observed.

Face detection is a necessary first-step in face recognition systems, with the reason of localize and extract the face region from the background. It also has a number of applications in areas such as content-based image recovery, video coding, video conferencing, crowd observation, and intelligent human–computer interfaces. We have taken skin color as a tool for detection. This technique works well for all types’ faces which have a specific complexion varying under definite range. We have taken real life examples and simulated the algorithms in MATLAB successfully. This paper concentrates on the input images are converted to the YCbCr model to collect the value Y,Cb,Cr. and check whether these values are satisfied with the threshold values. If the pixels are in the range of threshold then that pixels will be considered as skin region otherwise it is a non skin region. This paper defined algorithm has been tested on various real time frontal images and gets better results for the YCbCr color model.
Optimization of Acoustic Echo and Noise Reduction in Non Stationary Environment
Authors: R. Vincy , William J.
Published: January 2023

Optimized speech enhancement method combines acoustic echo reduction and noise reduction in a unified framework for non stationary environment. Simultaneous optimization of noise and echo reduction is already done in stationary environment. In most of the times in transmission, signal properties change over time. We need to remove the artifacts of sound in those conditions. Recursive least square method proposed for noise and echo reduction. It gives little amount of mean square error and better results. Normally, partial optimization of acoustic echo reduction and noise reduction does not lead to total optimization. A cascade method of multiple functions causes mutual interference between these functions and degrades eventual speech enhancement performance. Unlike cascade methods, the proposed method combines all functions to optimize eventual speech enhancement performance based on a unified framework, which is also robust against the mutual interference problem. With the proposed method, in addition to time-invariant linear filters, time-varying filters are used to reduce residual acoustic echo signal, and background noise signal which cannot be reduced using time-invariant filters. These time-invariant filters and time-varying filters are also optimized based on a unified likelihood function to avoid the mutual interference problem. Under this, all the parameters are optimized simultaneously based on the expectation-maximization algorithm and calculates a minimum mean squared error estimate of a desired signal. The experimental results show that the proposed method is superior to the cascade methods.

Authors: M. Mohamed Samsudeen
Published: January 2023

The aim of this study is to develop a Inductor coupled single input multiple output (SIMO) dc–dc converter. The proposed converter can boost the voltage of a low-voltage input power source to a controllable high-voltage dc bus and middle-voltage output terminals. The high-voltage dc bus can take as the main power for a high-voltage dc load or the front terminal of a dc–ac inverter. Moreover, middle-voltage output terminals can supply powers for individual middle-voltage dc loads or for charging auxiliary power sources (e.g., battery modules). As a result the objectives of high-efficiency power conversion, high step up ratio, and various output voltages with different levels can be obtained.

Authors: G. Raja , T. Meganathan
Published: January 2023

Multilevel inverters have grasped attention in the past few years as power converters in many applications. They are advantageous over the conventional two-level inverters because of the capability of reducing the lower order harmonic contents by increasing the number of levels. Many studies and research have been done for generation of modulating signals for multilevel inverters. Modulation signal generation methods for these inverters include staircase modulation, sine-triangle carrier modulation, space vector modulation etc. Various topologies of multilevel inverter provides several advantages including lower voltage stress, higher efficiency, lower EMI, better waveform and improved THD. This paper presents the development of Altium FPGA as a control circuit for generation of the digital pulse width modulation (DPWM) signal for the single-phase cascaded H-bridge multilevel inverter. The FPGA chip is chosen for the hardware implementation due to its ability to produce accurate results at a high computational speed. Counter based digital pulse width modulation (DPWM) for increased resolution without unnecessarily increasing the clock frequency is used. In addition to Altium Nanoboard FPGA, Xilinx System Generator/MATLAB software has been used for simulation and verification of the proposed circuit before implementation. The simulation and experimental results are in close agreement.

Nowadays PWM control technique has become an integral part of the most power electronics system. This technique is the most suitable one for controlling the output voltage of a power rectifier. In this paper the performance of the proposed module is analyzed for various Hybrid modulation techniques and the most suitable technique is identified on the basis of Total Harmonic Distortion present in the supply current waveform. Hybrid PWM technique is used to control Gate signal of power switches of single phase power rectifier. By this way, ON and OFF time of circuit MOSFETs can be controlled to obtain the desired DC output voltage. The performance of the power rectifier with the Hybrid PWM technique is promising and attractive for harmonics free power supply applications.
