Likewise, numbers of reconstruction projects had also been forwarded and are being undertaken at different levels of implementation by respective authorities. In a figurative interpretation, NRA is at the verge of completion of reconstruction works in substantial numbers. However, the process of reconstruction still remained ambiguous to the communities of major cultural heritage sites plundering to dilemmas in implementation, of which many are still in disputes. Apart from the monument reconstruction in these areas, reconstruction works of private heritages have plunged into a prime concern on economic development through tourism promos unlikely to keeping cultural heritage essence, while the latter seems awful in fulfilling their basic demands of livelihood. This paper assumes either of these deeds is rampant on the long run of heritage conservation major goals. \u0000Thus, it considers major 3 areas concentric to Kathmandu valley heritage sites i.e. Bungamati, Sankhu and Panga that are in the process of reconstruction and identify probable consequences brought over by ongoing enigmas among the communities and authorities in due course of reconstruction. It also seeks to assess them through the prism of authenticity criteria and sustainability measures of heritage assets based on community participation in reconstruction process. Ultimately, it highlights the necessity of instant and rapid reconstruction as well as conservation measures in Kathmandu valley by identifying the real owners, authorities and beneficiaries responsible for keeping intact the heritage resources.

Concrete fracture, catastrophic failure, spalling of concrete and non-quake resistance, with the application of a load are major problems of the current scenario in the concrete world (Mindess, 2009). This paper tries to solve this type of problem by using the natural fibers and some additives which are under patient right. The researcher of this paper has developed a prefab panel which may be the substitute product of brick, ACC block, interlocking block, EPS panel, and local prefab panel. The utilization of industrial waste to usable products for construction is a major challenge that the researcher has taken. The paper shows that product can be made economical and able to reduce environmental challenges. Ingredients like human hair, EPS, chemical agent, cement, fly ash, water, and fiberboard are utilized in a certain time and fixed condition to complete the formation of the Fiber-reinforced concrete panel. The panel was found to have multi-function like a light in weight, fireproof, and flexibility which was its main USP (Unique Selling Point). The researcher thinks this product might change the perception of Nepalese customer, who thinks prefab as a costly and less strength product. Nepal political instability and dependent culture on foreign country shows an impossible possibility to use an artificial fiber and imported fly ash (ITC, 2017). This paper also presents the Nepalese market perception through the business model canvas, a business strategy that can be taken, hindrance, and the possibility to use human hair fiber, fly ash and recycled EPS to complete finished goods.","PeriodicalId":183221,"journal":{"name":"SCITECH Nepal","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116619290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improper material management systems lead to adverse impact on time, cost and quality of the construction projects. Most of the construction projects have not been completed on time, partly due to the poor material management system. Therefore, the aim of this study is to assess status of material management system (MMS) of building construction projects. Sixteen government building construction projects were selected in Kathmandu Valley for determining existing practices of MMS. Questionnaires survey, field visit and key informant interviews (KII) were used to collect the primary data and related literatures and documents available at site were reviewed for collecting secondary data. Quantitative and qualitative techniques were used as data collecting tools. MS Excel tool was used to analyse the data. From the study, it is found that manual record keeping system was used for MMS. About 71.43 % of projects did not use automatic loading/ unloading system and did not give priority to the quality of materials for MMS. Nearly 75 % of projects have implemented well managed store house in site as per material type and also focused on centralized storing system. None of the projects used any new technology of MMS in Building Construction Projects. It leads to the cost overrun on Building Construction Projects.","PeriodicalId":183221,"journal":{"name":"SCITECH Nepal","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127891841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper focuses on the analysis of EEG signal to detect the presence of the epileptic seizure prior to its occurrence. The result could aid the individual in the initiation of delay sensitive diagnostic, therapeutic and alerting procedures. The methodology involves the multi resolution analysis (MRA) of the EEG signals of epileptic patient. MRA is carried out using discrete wavelet transform with daubechies 8 as the mother wavelet. For EEG data, the database of MIT-BIH of seven patients with different cases of epileptic seizure was used. The result with one of the patients showed presence of a unique pattern during the spectral analysis of the signal over different bands. Hence, based on the first patient, similar region is selected with the other patients and the multi-resolution analysis along with the principal component analysis (PCA) for the dimension reduction is carried out. Finally, these are treated with neural network to perform the classification of the signal either the epilepsy is occurring or not. The final results showed 100% accuracy with the detection with the neural network however it uses a large amount of data for analysis. Thus, the same was tested with dimension reduction using PCA which reduced the average accuracy to 89.51%. All the results have been simulated within the Matlab environment.","PeriodicalId":183221,"journal":{"name":"SCITECH Nepal","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123259756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quality of power is measured by voltage stability and profile of voltage. The voltage profile is affected by the losses in distribution system. As the load is mostly inductive on the distribution system and requires large reactive power, most of the power quality problems can be resolved with requisite control of reactive power. Capacitors are often installed in distribution system for reactive power compensation. This paper presents two stage procedures to identify the location and size of capacitor bank. In the first stage, the load flow is carried out to find the losses of the system using sweep algorithm. In the next stage, different size of capacitors are initialized and placed in each possible candidate bus and again load flow for the system is carried out. The objective function of the cost incorporating capacitor cost and loss cost is formulated constrained with voltage limits. The capacitor with the minimum cost is selected as the optimized solution. The proposed procedure is applied to different standard test systems as 12-bus radial distribution systems. In addition, the proposed procedure is applied on a real distribution system, a section of Sallaghari Feeder of Thimi substation. The voltage drops and power loss before and after installing the capacitor were compared for the system under test in this work. The result showed better voltage profiles and power losses of the distribution system can be improved by using the proposed method and it can be a benefit to the distribution networks.","PeriodicalId":183221,"journal":{"name":"SCITECH Nepal","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114841891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social media is one of the notable sources of such data streams. While social media streaming has received a lot of attention over the past decade, the ever-expanding streams of data presents huge challenges for learning and maintaining control. Dealing with billions of user’s data measured in pet bytes is a demanding task in itself. It is indeed a challenge to mine such dynamic data from social networks in an uninterrupted and competent way. This paper is purposed to introduce social data streams and the mining techniques involved in processing them. We analyse the most recent trends in social media data stream mining to translate to the detailed study of the matter.
