Public Health Impact of Particulate Matter Pollution in Nepal: A Review | IJSTE JOURNAL VOL 3, ISS 4

Public Health Impact of Particulate Matter Pollution in Nepal: A Review

Worldwide air pollution continues to pose a significant threat to human health. Air pollution is a major environmental risk to health. According to Yale Environmental Performance Index (EPI) 2016, Nepal ranked on 149 among 180 countries in terms of air quality. Nepal’s capital city Kathmandu, which also chokes beneath a blanket of pollution, there is neither data nor any proper information available regarding air quality. Different natural and anthropogenic reasons are responsible for the emission of complex mixtures of air pollutants, many of which are harmful to health. Particulate matter also consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. Particulate matter affects more people than any other pollutant. There is a close, quantitative relationship between exposure to high concentrations of small particulates (PM10 and PM2.5) and increased mortality or morbidity, both daily and over time. The effects of particulate matter on health occurs at levels of exposure currently being experienced by many people both in urban and rural areas and in developed and developing countries. Fine particles are more dangerous than coarse particles, as PM2.5 can penetrate into the alveolar regions of the lungs these particles may cause serious damage to developing lungs of children. Ambient particulate matter is responsible for harmful effects on health, even in the absence of other air pollutants. Long-term exposure to current ambient particulate matter concentrations may affect the lungs of both children and adults and may reduce life expectancy by a few months, mainly in subjects with pre-existing heart and lung diseases. Acute exposure studies that evaluated short-term (usually daily) variations in health end points such as hospitalizations, and lung function associated with short-term variations in levels of pollution. Long term (months, years) exposure can cause some chronic health issues like includes, increased mortality rates, reduced survival times, chronic cardiopulmonary disease and reduced lung function. The issues of particulate matter pollution should be addressed by the national level policy that can be applied at different public and private sectors. The government of Nepal has introduced several policies, legislation and standards related to air pollution. Those policies and legislation need to be implemented to fight against the pollution.

A Secured Framework for Sharing Data using Diverse Image Media and Image Encryption | IJSTE JOURNAL VOL 2, ISS 12

A Secured Framework for Sharing Data using Diverse Image Media and Image Encryption

Secret images in shares that are either encoded and stored in a digital form or printed on transparencies or are hidden in Conventional visual secret sharing (VSS) scheme. Appearance of the shares as noisy-like pixels or as meaningful images; during the transmission of the shares it can cause suspicion and increase interception risk. Hence, transmission risk problem for the secret itself and for the involved participants in this scheme will be suffered in VSS schemes. To solve the transmission risk problem, we proposed a natural-image-based VSS scheme (NVSS scheme) in which secret images is shared via various carrier media so that the secret and the participants can be protected during the transmission. The proposed scheme can share one secret image over n selected natural images (called natural shares) and one noise-like share. Any kind of photos or hand-painted pictures in digital form or in printed form can be the natural shares. Based on these natural shares and the secret image the noise-like share is generated. The transmission risk problem can be reduced as the unchanged natural shares are diverse and innocuous. We also hide the noise like share to reduce the transmission risk problem. We have also used planned randomness in which during steganography the pixels are not stored in the carrier image original position instead the key is added to the original pixel position to obtain the new position which added additional security. Also we used alpha channel watermarking to find whether the images pixels are changed or not if changed then we can’t get the original image.

Effect on Concrete Strength Due to Addition of Fiber | IJSTE JOURNAL VOL. 3, ISS 1

Effect on Concrete Strength Due to Addition of Fiber

Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, G.I., carbon, glass, asbestos, polypropylene, jute etc. The addition of these fibers into concrete mass can dramatically increase the compressive strength, tensile strength, flexural strength and impact strength of concrete. FRC has found many applications in civil engineering field. Based on the laboratory experiment on fiber reinforced concrete (FRC), cube and cylinders specimens have been designed with steel fiber reinforced concrete (SFRC) containing fibers of 0% and 0.5% volume fraction of hook end Steel fibers of 53.85, 50 aspect ratio. Comparing the result of FRC with plain M20 grade concrete, this paper validated the positive effect of different fibers with percentage increase in compression and splitting improvement of specimen at 7 and 28 days, analyzed the sensitivity of addition of fibers to concrete with different strength.

Visual Secret Sharing Provides Security to the Electronic Medical Report | IJSTE JOURNAL VOL 2, ISS 5

Visual Secret Sharing Provides Security to the Electronic Medical Report

the importance of secret image sharing method is to provide privacy and security, which is an important concern in the medical field. Providing authentication and security to medical data is a challenging task. So as to overcome this challenge the visual secret sharing scheme is proposed. In this method transform the secret pixels into m-array notational system. A threshold value is set in order to reconstruct the original image. The original image is being encrypted and is then shared into proportions .A cover image is being provided to each of these shares. The stego image of high quality is being formed. While reconstructing the image the threshold value along with the minimum number of shares is given. This technique is implemented in the medical field for storing and sharing Electronic Medical Report.

Modification in Weld Overlay for Productivity and Corrosion Resistance | IJSTE JOURNAL VOL 2, ISS 2

Modification in Weld Overlay for Productivity and Corrosion Resistance

This paper focuses on the modification in overlay welding in the industries. Industries have increased the possibility of severe corrosion and wear in process pressure vessels. The industries must upgrade the corrosion and wear performance of these main important parts. It is essential to surface non-alloyed or low alloy base materials with high-alloy cladding. The Electro slag strip cladding (ESSC) or Electro slag welding (ESW), Gas metal arc welding (GMAW) processes are appropriate for applying welded deposits over large surface areas. The paper indicates how the modification helped in order to improve the production rate as well as corrosion resistance properties, hence improvement in the quality of the weld overlay. How production is increased with the use of Electro slag strip cladding instead of Gas metal arc welding is discussed in this paper. Material used for Electro slag strip welding is also discussed.

Faults in Transformer Winding and Probing their Occurence by S-Transform and RBF Neural Network Technique | IJSTE JOURNAL VOL 2, ISS 9

Faults in Transformer Winding and Probing their Occurence by S-Transform and RBF Neural Network Technique

Now a days significant enhancement of certainty, reliability and economics of the power transformer is an important topic in power system engineering because among all equipment as for expedition used in electrical systems power transformer is one of the most costly piece of equipment. So that accurate diagnosis of fault has been always been a major issue. Simulation studies based on transient model of transformer winding enhance understanding of surge voltage and fault current waveforms. Those are non-stationary in nature. The non -stationary nature of current waveforms inside the transformer winding requires the model parameter to be both time and frequency dependent. it will help to detect type of fault as well as location of occurrence using simulation studies. This paper aims to present a technique for diagnosis of the type of the fault and location of occurrence. . The proposed method is based on a transient model based transformer under impulse test and S-Transform with good time frequency resolution for all frequencies (multi resolution). S-Transform is used to produce a stock well coefficient vector which utilized as inputs testing set to a Radial Basis Function Neural Network (RBF). The fault conditions are simulated by the variation of fault location according to inter turn winding of power transformer or disc. The training is conducted by programming in MATLAB. The robustness of the proposed scheme is investigated by synthetically polluting the simulated voltage signals with White Gaussian Noise. The suggested method has produced fast and accurate results. Estimation of fault location is intended to be conducted in future.

Experimental investigation on effect of EGR on biofuel fueled HCCI engine using external fuel vaporizer- A Technical review

The Homogeneous charge compression ignition (HCCI) combustion is an alternative to current engine combustion systems. The research in HCCI is being carried out to use it as a method to reduce emissions and also enhance engine efficiency. HCCI has the potential to nearly eliminate NOx emissions while increasing efficiency as in diesel engine. HCCI adapts a pre mixture of gas-phase fuel and air being burned spontaneously and entirely by an auto ignition process. Homogeneous Charge Compression Ignition (HCCI) engines promises a high thermal efficiency combined with low levels of nitrogen oxides and particulate matter emissions. The purpose of this study is to summarise the effect of alternative fuel when used in the HCCI engine combustion process. Modification of single cylinder diesel engine runs on HCCI mode with diesel and biofuel. Installation of EGR system on HCCI engine. To study the effect of EGR rate on the engine exhaust parameter like nitrogen oxides (NOX), carbon oxides (CO and CO2), particulate matters (PM) and unburnt hydro carbons (UHC) by running the engine on HCCI mode with biofuel.

Distributed Manufacturing #IJSTE JOURNAL#

IJSTE - International Journal of Science Technology and

 Engineering

Subject: 

Distributed Manufacturing

Distributed manufacturing turns on its head the way we make and distribute products. In traditional manufacturing, raw materials are brought together, assembled and fabricated in large centralized factories into identical finished products that are then distributed to the customer. In distributed manufacturing, the raw materials and methods of fabrication are decentralized, and the final product is manufactured very close to the final customer.

In essence, the idea of distributed manufacturing is to replace as much of the material supply chain as possible with digital information. To manufacture a chair, for example, rather than sourcing wood and fabricating it into chairs in a central factory, digital plans for cutting the parts of a chair can be distributed to local manufacturing hubs using computerized cutting tools known as CNC routers. Parts can then be assembled by the consumer or by local fabrication workshops that can turn them into finished products. One company already using this model is the US furniture company AtFAB.

Current uses of distributed manufacturing rely heavily on the DIY “maker movement”, in which enthusiasts use their own local 3D printers and make products out of local materials. There are elements of open-source thinking here, in that consumers can customize products to their own needs and preferences. Instead of being centrally driven, the creative design element can be more crowdsourced; products may take on an evolutionary character as more people get involved in visualizing and producing them.

Distributed manufacturing is expected to enable a more efficient use of resources, with less wasted capacity in centralized factories. It also lowers the barriers to market entry by reducing the amount of capital required to build the first prototypes and products. Importantly, it should reduce the overall environmental impact of manufacturing: digital information is shipped over the web rather than physical products over roads or rails, or on ships; and raw materials are sourced locally, further reducing the amount of energy required for transportation.

If it becomes more widespread, distributed manufacturing will disrupt traditional labour markets and the economics of traditional manufacturing. It does pose risks: it may be more difficult to regulate and control remotely manufactured medical devices, for example, while products such as weapons may be illegal or dangerous. Not everything can be made via distributed manufacturing, and traditional manufacturing and supply chains will still have to be maintained for many of the most important and complex consumer goods.

Distributed manufacturing may encourage broader diversity in objects that are today standardized, such as smartphones and automobiles. Scale is no object: one UK company, Facit Homes, uses personalized designs and 3D printing to create customized houses to suit the consumer. Product features will evolve to serve different markets and geographies, and there will be a rapid proliferation of goods and services to regions of the world not currently well served by traditional manufacturing.
