Abstract: Digital video recorder (DVR) being popular options for home and organisation security, seizure of DVR in different types of crime scene is increasing constantly. Though the resident operating system of the DVR and the embedded file recovery system can be used for retrieval of footage, difficulty arises due to unavailability and inaccessibility of DVR. In this situation recovery of footage from a DVR hard disk is only available option. But, in majority cases standard data recovery software used for forensic examination/ data recovery of hard disks used in computer and desktop do not show files of DVR hard disk. Though, footages can be carved from raw disk, identification of proprietary file..........

Abstract: In today's world number of devices are used in order to complete the work. These devices generate a lot of data and also need to communicate with other devices. It is necessary to analyze the data generated by these machines. When devices want to connect it is necessary to have an internet connection. IoT is basically a network which consists of devices, vehicles, home appliances, software's, sensors, actuators, and they are connected to collect and exchange the data. In order to achieve this data mining and IoT can be utilized. The collaboration of IOT and Data Mining will make various tasks simpler. Merger of data mining and IoT is discussed in this paper. This paper represents Data mining challenges, and Data mining issues with IOT.

Abstract: Automatic text summarization is the technique of distilling the most important information from a text or a set of text. The amount of online information services, social media and other digital format documents is increasing gradually which has necessitated intensive research in the area of automatic text summarization. Text summarization is the most challenging task for information retrieval. It requires integration of techniques, implementation of hybrid schemes, including NLP, data mining and analytics, as well as optimization and linguistic theories. Various researchers from the NLP community have been addressing it from various perspective in different domains and..........

Abstract: This paper will describe the application of IZAT software to reduce B3 waste, regarding to Indonesia Government Regulation No. 101 of 2014 on the Management of Hazardous and Toxic Wastes defines Hazardous and Toxic Substances. The IZAT software designed and use by PT PJB Gresik Power Plant, Gresik, Indonesia to reduced B3 waste as shown in Figure 1. The software is based on Android which was developed and used by the K3 Field PT PJB UP Gresik to monitor K3 infrastructure, including fire extinguisher. Using this application, fire extinguisher that has approached the expiration date can be taken and used for internal fire fighting training activities. Therefore, it can reduce the volume of B3 waste from expired dry chemicals. The utilization of IZAT application can reduce B3 waste and provide additional saving to PT. PJB UP Gresik. It exhibit the great spirit of green in PT. PJB UP Gresik. In future, The method can be applied to reduce waste in others material and increase saving

Abstract: Self-Compacting Concrete (SCC), which flows under its own weight and does not require any external vibration for compaction, has revolutionized concrete placement. SCC, was first introduced in the late 1980's by Japanese researchers, is highly workable concrete that can flow under its own weight through restricted sections without segregation and bleeding. Such concrete should have a relatively low yield value to ensure high flow ability, a moderate viscosity to resist segregation and bleeding, and must maintain its homogeneity during transportation, placing and curing to ensure adequate structural performance and long term durability. The successful development of SCC must ensure a good balance between deformability and stability. Researchers have set some guidelines for mixture proportioning of SCC, which include i) reducing the volume ratio of aggregate to cementations material; (ii) increasing the paste volume and water-cement ratio (w/c); (iii) carefully controlling the maximum coarse aggregate particle size and total volume; and (iv) using various viscosity modifying admixtures (VMA).

Abstract: construction and subsequent maintenance of pavements in good condition has become quite problematic During monsoon season the natural subgrade soils become soft and pose serious problems ,To the movement of vehicular traffic, Instead of cutting out and replacing the unstable soil, soil adjustment is the only alternative as it saves lot of time and millions of money too. Soil adjustment can be defined as the change of the soil properties by synthetic or physical means keeping in mind the end goal to improve the designing nature of the soil. This work presents the result of comprehensive laboratory investigation over behaviour of stabilized loose soft soil using Terassil and Zycobond as nano-chemical based stabilizer. The soil is stabilized in different proportions and combination of Terassil and Zycobond along with cement

Abstract: Soil stabilization can be explained as the alteration of the soil properties by chemical or physical means in order to enhance the engineering quality of the soil. The main objectives of the soil stabilization are to increase the bearing capacity of the soil, its resistance to weathering process and soil permeability. which can be done by use of controlled compaction or addition of suitable admixtures like cement, lime and waste materials like fly ash, phosphor gypsum etc. This new technique of soil stabilization can be effectively used to meet the challenges of society, to reduce the quantities of waste, producing useful material from non-useful waste materials. Plastic waste such as bottles and plastic granules is used to as a reinforcement to perform the maximum dry density, CBR, UCS studies........

Abstract: Concrete as a construction material is widely used in India with annual consumption exceeding 100 million cubic meters. Conventional Ordinary Concrete which is designed on the basis of compressive strength does not meet many functional requirements since it is found deficit in aggressive environments conditions, time of construction, energy absorption capacity, repair and retrofitting jobs etc. So, there is a need to design High Performance Concrete (HPC) which..........

Abstract: Expansive soils are susceptible to detrimental volumetric changes with changes in moisture content causes distortions to the structures constructed on these soils. Use of calcium based stabilizes to enhance clay's engineering properties is a common practice in road subgrade improvement. The addition of a calcium based stabilizer increases the calcium content of the soil to reduce the diffuse double layer by cation exchange and leads to flocculation and agglomeration of the clay microstructure. The addition of calcium hydroxide (Ca(OH)2) allows cementitious hydrates to form, via pozzolanic reactions, that increase soil strength. Problems can arise when sulfate and alumina are readily available within the natural state of the soil. There are many methods of stabilization of sub grade.......
