Why has terrorism spread in the 21st century?[ ]


The author believes that terrorism did not spread during the period of Ottoman rule because the Ottoman Empire was acting as a political empire intended to expand and extend its political influence, that is, the Ottoman Empire, despite carrying the banner of protection of Islam, but were not governed by the theory of Islam, . Terrorism spread when Islamic political movements came up with political theories of governance, and they believed that these theories should be applied on the ground.

Standalone Wind Energy Conversion System Assisted with Low Cost Battery Energy Storage System[ ]


Present energy need heavily relies on the conventional sources. But the limited availability and steady increase in the price of conventional sources has shifted the focus toward renewable sources of energy. Of the available alternative sources of energy, wind energy is considered to be one of the proven technologies. With a competitive cost for electricity generation, wind energy conversion system (WECS) is nowadays deployed for meeting both grid-connected and stand-alone load demands.

Model of Ecotourism Development Heart Of Borneo (HoB) Through Dynamic Systems Approach[ ]


Many countries in the world are developing the tourism industry, including developing countries in Southeast Asia such as Indonesia. The purpose of this research is to design a model of sustainable HoB ecotourism in Kapuas Hulu District through dynamic system approach. Development of HoB ecotourism focuses on two national parks is located in Kapuas Hulu District, ie TNBK, and TNDS. The scenario simulation suggests that the increase of non-tax revenues which can encourage the building of infrastructure in Kapuas Hulu Regency. Based on the number of tourists and non-tax revenues obtained through the development of ecotourism HoB can illustrate that forest conservation activities can be an alternative solution in ecotourism based forest management methods in Kapuas Hulu District. Supported by optimistic scenario results shows that serious HoB ecotourism management can generate non-tax state revenues that can encourage better infrastructure development in the district.

Legal Consequences of Non-Contractual Promises in Construction Industry[ ]


Contract law is in the process of evolution if not revolution. As the construction industry is notorious for contractual disputes, one cannot underestimate the significance of remaining well informed of these developments. The developments in contract law have been caused by a shift in legal thinking. Legal thinking has shifted from interpreting contracts based solely on their express and implied terms to nowadays looking at the circumstances of a case as a whole. Looking beyond the terms of a contract has consequences for how negotiations are to be considered by a court of law. Traditionally, negotiations have been seen as informal discussions. Unless something mentioned in negotiations was subsequently framed as a term of the contract it had no legal consequence. Recent case authority has rejected this proposition and so it is deemed as being appropriate to state contract law as being in the process of revolution.

Experimental Study of the Lattice Constant and Lattice Spacing Of Potassium Bromide by Laue and Debye Scherer Methods[ ]


This paper presents the calculation of Lattice parameters of the structure of crystals of Crystalline and powder ionic salts of KaBr by a x-rays LD apparatus. The crystals structure study is important to get knowledge about the different characteristics of materials just like by kinetic molecular theory. Due to analysis of materials on the basis of diffraction phenomena, the field has been made more growing and sophisticated. X-rays diffraction by points of the lattice provide radiograph on special Dentus films using X-ray machine. X-ray diffraction technique is an easy approach to crystallography as compared to electron and neutron diffraction due to its ease, availability and easily handling. By developing the film under darkroom conditions, the data is collected by indexing the pattern of spots and rings or the images and is tabulated for different parameters by calculation of the sample through Laue and Debye Scherer methods. The obtained results are much closed to the actual results. This research work will also be helpful in the crystallography by different techniques of different alkali halides samples.

Scientifical research on the parameter reliability of risk technical systems in mechanical engineering[ ]


Operational capabilityability on the risk technical systems (RTS), creep in the mechanical engineering is determined from the assembly of the parameter assignment and allow the borders to change (i.e., the tolerance field). Breaking of the operational capabilityability is caused by the release (deviation) even on one of the the parameter, set out is determined from the tolerance field in the normative technical documentation. This breaking is associated with the occurrence of a condition, requiring investigation a function of the catastrophe (FC) on RTS.

The determination of the velocity of the vehicle according to the slide marks of vehicle while moving through a curve[ ]


During the movement of the vehicle through a curve whilst surpassing critical slide velocity there appears not only sliding, but also the uncontrolled movement of the vehicle. In this process, aside from the usual parameters which influence the critical slide velocity of the vehicle in a curve there is also importance to the driver’s actions. In the occasions where the vehicle slides and slide marks appear we have the problem of determining the speed of the vehicle at the point where the driver lost control.

Similarity in Arabic Continuous Speech Recognition[ ]


In this paper, Dynamic time warping (DTW) algorithm is proposed to find the similarity between Arabic words based on 39 coefficients of MFCC features. The audio samples collected from different nationalities (Jordan (J), Malaysia (M), Pakistan (P), Nigeria (N),Iran(I) and Yemen(Y)) of continuous Arabic words. Then the MFCC coefficients are extracted from the database and DTW is introduced by Sakoe Chiba and it has been utilized as features matching techniques and recognition, where the voice signal itself tends to have different temporal rate. Training and testing phases are done using 39 coefficients MFCC features. The experimental results are provided using MFCC and Delta Delta Coefficients (DDMFCC). It is recommended that higher recognition rates can be accomplished using (DDMFCC) with DTW which is valuable for different time varying speech Arabic recognition words.
