Evaluation of Software Requirement Specification Based on IEEE 830 Quality Properties
Authors: Stephen E. , Mit E.
Published: September 2020

Software requirement specification (SRS) documented an essential requirement of software and its external interface. Many studies found the quality of SRS, but lack of the informality organizing of document and representation of functional requirement. This paper aims to evaluate the quality properties of the software requirement specification (SRS). There are four quality properties to be assessed, which are completeness, correctness, preciseness, and consistency. Completeness quality is used to evaluate the structure of the SRS document; meanwhile, the other three qualities used to evaluate the functional requirement. The measurement for each quality properties has been proposed in the previous study. The evaluation process involves a few stages. In short, the prototype would extract text through the provided document, do a calculation, and came out with the result in the form of a similarity percentage. The prototype designs in such ways it minimizes the user interference. Those resulted in reducing human error. Corpus contains libraries of term and topic are expected to increase the reliability of detection. The corpus includes topics extracted from IEEE 830 standard, vague word, terms represent Create, Read, Update, and Delete (CRUD) operation, and terms denote possible datatype. The extracted functional requirement would be refined based on the Requirement Boilerplate (RB) template. RB adopted in the study to ensure the consistency of functional refinement requirements. The percentage of similarity is determined based on comparison with IEEE 830 standard. The rate of the result of each quality properties reflects the quality of the software requirement specification.

Published: September 2020

This paper focuses on the Vehicle Routing Problem with Simultaneous Pickup and Delivery (VRPSPD) issue. VRPSPD is one of the extended problems related to the usual Vehicle Routing Problem (VRP). VRPSPD consists of both linehaul customers and backhaul customers with a known demand. In VPRSPD, only a single depot can receive and supply the loads. The vehicles can only visit each customer once and can serve all customers simultaneously by delivering or picking up the loads within a limited capacity. VPRSPD is a NP-hard problem. The huge data size has increased the difficulty for it to be solved by using mathematical programming or combinatorial optimisation. A heuristic approach based on the Variable Neighbourhood Search (VNS) is proposed. Heuristic based solutions offer feasible solutions that are approximately accurate to the exact solution. It is one of the most popular solutions to solve a complex problem. In this research, the algorithm solution consists of two main phases. A simple heuristic is used to generate the initial solution in the first phase. Then, the feasible solution obtained in the first phase will become the initial input for the improvement phase which applied the VNS algorithm. The proposed algorithm is tested using a list of benchmark dataset. The result obtained is compared with the best solution that can be found from the literature research. The comparison result shows that the heuristic algorithm is favourable to be used for this kind of vehicle routing problem.
A New Technique to Reduce the Cogging Torque of Integral Slot Number in Permanent Magnet Synchronous Machine
Authors: Siregar Marsul , Wohon Dolly Ramly , Nur Tajuddin
Published: September 2020

This paper proposed a new cogging torque reduction technique of integral slot number in the permanent magnet synchronous machine (PMSM). The purpose of the proposed new technique simulated on the PMSM with 48 slot/6 pole structure. In the study, the magnet edge of the PMSM was slotted to minimize the cogging torque while the stator core has remained natural. Slotting in magnet edge is one of the techniques to reduce the cogging torque in PMSMs, which has been existed in the previous research. In the proposed structure, we employed the two steps of slotting in magnets edge as one of the cogging torque reduction techniques. In this paper, authors have investigated three permanent magnet synchronous machine with different magnet structure has been studied and compared. The proposed permanent magnet synchronous machine with employed two steps of slotting has shown to promise the best of cogging torque reduction. The performance of the permanent magnet synchronous machine studied has been computed and analyzed by finite element analysis. It is found that the smaller cross-section area of magnet pole results in the decrement of cogging torque and air gap normal flux density in the PMSM. The new slotting in the magnet edge reduces the magnet pole cross-section and the cogging torque. The cogging torque of the proposed structure could be reduced around 98.8 % compared with the initial structure. The two steps of slotting could reduce the cogging torque of integral slot number in permanent magnet synchronous machine significantly.

Published: September 2020

Recommendation systems or recommender system (RSs) is one of the hottest topics nowadays, which is widely utilized to predict an item to the end-user based on his/her preferences primary. Recommendation systems applied in many areas mainly in commercial applications. This work aims to collect evidence of utilizing social network information between users to enhance the quality of traditional recommendation system. It provides an overview of traditional and modern approaches used by RSs such as collaborative filter (CF) approach, content-based (CB) approach, and hybrid filter approach. CF is one of the most famous traditional approaches in RSs, which is facing many limitations due to the lack of information available during a performance such as Cold start, Sparsity and Shilling attack. Additionally, this content focused on the role of incorporating a trust relationship from the social network to enhance the weaknesses of CF and achieve better quality in the recommendation process. Trust-aware Recommendation Systems (TaRSs) is a modern approach proposed to overcome the limitations of CF recommendation system in a social network. The trust relationship between users can boost and enhance CF limitations. Many researchers are focusing on trust in the recommendation system but fewer works are highlighting the role of trust in the recommendation system. In the end, limitations, and open issues of the current picture of the recommendation system come across.

Published: September 2020

The diverse control techniques have been combined with fractional calculus to enhance the control system performance. This paper presents an efficient fractional-order model reference adaptive controller (FOMRAC) design, which aims to demonstrate the solution for temperature reference tracking and cross-coupling rejection in the multi-input multi-output thermal system as well as cognizing of power consumption saving constraints. The mathematical modeling, nonlinear dynamic characteristic details, and system identification of the thermal system are described while the fractional-order controller combined with a model reference adaptive control (FOMRAC) based on MIT rule is developed so that to create the nonlinear adaptive mechanism which enables the excellent performance to control the multi-input multi-output thermal system. Likewise, a decoupling compensator is constructed to remunerate the effect of the cross-coupling interaction. The validation of the proposed control scheme is performed through the Matlab simulation and the experiment on the multi-input multi-output thermal system. The results illustrated the FOMRAC technique in which the controller's adjustable parameters can provide efficiency stability and performance to minimize the settling time and percent overshoot of the control system response. Besides, the analysis of the power consumption in the control system is addressed to reinforce the useful ability of the proposed method compared with the integral-order model reference adaptive controller (IOMRAC) and the traditional PID controller. The results revealed that the proposed FOMRAC technique exhibited much better than other methods because of the effective optimization of adaptive gain mechanism and fractional-order operators.

Using the MLR and Neuro-Fuzzy Methods to Forecast Air Pollution Datasets
Authors: Shukur Osamah Basheer
Published: September 2020

The forecasting of time series data is essential by following statistical and intelligent techniques. Particular matter (PM10) is a time series dataset used to scale the air pollution as a dependent variable while there are many types of pollutants used as independent variables. MLR model has been used as a traditional linear approach to forecasting PM10 data. Combining NF as a nonlinear intelligent method with MLR in a hybrid MLR-NF method has been proposed for improving PM10 forecasts and handling the nonlinearity of datasets. The forecasting results reflected that the hybrid method outperformed the traditional method. Although a multiple linear regression (MLR) model has been used for air quality forecasting depending on several meteorological variables in many recent studies, the MLR model is unable to identify the nonlinear pattern of these types of data. Malaysian datasets of PM10 and several climate pollutants will be studied in this paper. The objective of this study is to forecast PM10 and obtain the best results and minimum forecasting error. In this paper, the dependent variable will be forecasted by using traditional and intelligent methods. MLR has been used as a traditional method to forecast PM10. Neuro-fuzzy (NF) in the adapted copy, which calls the adaptive neuro-fuzzy inference system (ANFIS) is combined with MLR and used as an intelligent method to forecast PM10. The results reflect that MLR-NF outperformed MLR for forecasting PM10 data. In conclusion, MLR-NF can be used to forecast PM10 for more accurate results compared to traditional methods.

Demarcation Study on Reclaimed Asphalt Pavement Contents in Recycled Hot Mix Asphalt Mixtures for Wearing Course in Asphalt Pavements
Authors: Zemedkun Bereket Samuel , Takahashi Osamu
Published: September 2020

The present study evaluated reclaimed asphalt (RAP) containing hot mix asphalt (HMA) mixtures performance, to assess the effect of 5% RAP alteration on the marginal change in performance between 20%, 25%, and 30%. Then, the results from assessment were used to classify the RAP contents in HMA mixtures as low, moderate, and high by comparing the performance of the mixtures. The HMA specimen’s preparation followed the Marshall mix design procedure with a 12.5 mm nominal maximum aggregate size (NMAS). Rutting and stripping resistance were selected as the primary performance. The wheel tracking (WTT) and indirect tension strength (IDT) tests were done to assess rutting and stripping performance, respectively. The WTT results indicated that a mixture with 30% RAP performed well in rutting resistance, followed by 25% and 20% RAP mixtures. The results of the tensile strength ratio (TSR) from the IDT showed that mixtures with 0% RAP and 20% RAP were susceptible to stripping. On the other hand, mixture with the 25% RAP had good stripping resistance. From the test results, it was observed that RAP contents up to 20 % had similar performance as 0% RAP mixture. Mixtures containing 25% RAP and 30% RAP found better on rutting and stripping resistance. Based on the experiment results, the 5% variation in RAP content affects the performance of the mixtures significantly. The present study concluded that RAP content could be tiered as follows; up to 20 % is low content, above 20% to 30% as moderate, and above 30% is high content.

Published: September 2020

Most of the land in South Sumatera is the problematic soil, one of that is peat. Peat has low soil bearing capacity, and it becomes a problem when construction is built. Before the installation process, it is necessary to handle that soil. Soil improvement that can be done on peat to increase the bearing capacity value is the reinforcement method or physical stabilization. The results of research on woven bamboo and cerucuk are used as reinforcement material, which is expected to be an alternative to improve soil bearing capacity. The research methodology used was on the scale of the laboratory and analyzed by comparing the soil bearing capacity without reinforcement in bearing capacity ratio (BCR). The maximum bearing capacity with cerucuk reinforcement and without woven bamboo is 39.33 kPa with variations of the two outer rods of the left and right sides from 750 angle toward the foundation plane. However, using the 3 layers of reinforcement woven bamboo that is combined with cerucuk, which has diameter 1,5 cm and length 60 cm generates the highest soil bearing capacity value. The maximum of bearing capacity is 58 kPa. The BCR is 10,88 or in percentage is 988,2%, or 10 times greater than bearing capacity without reinforcement. So, it can be inferred that woven bamboo and cerucuk are used as an alternative to improve bearing capacity on peat soil.

The growing international trade needs a logistic system managing the transportation system to create continuity in its process. Indonesia, as a country having land borders with neighboring countries, needs research about the freight transportation system with those different characteristics. Meanwhile, there is a tendency where the shift of the freight model paradigm results in the movement of the aggregate analysis approach to disaggregate or agent-based approach. With the need to consider the role and influence of actors’ decisions in the analysis-based of freight transportation, the agent-based model will become will be a supporting tool to analyze freight transportation. This paper will identify and elaborate on the actors or stakeholders having roles in the freight transportation system in cross borders, mainly the marine product commodities. To determine the most significantly influential stakeholders in the analysis of freight transportation in the cross-border area, we used the analytical network process (ANP) method. ANP is the improvement of AHP Analytical Hierarchical Process (AHP) by referring to the thoughts that there is a correlation in the network form between elements where ANP enables the occurrences of inner dependence within a set (clusters) of elements and outer dependence among different sets (clusters). Based on the analysis using ANP, we found that the company owners are the most influential party followed by governments, employees, and customers.  The link of result of stakeholder mapping and the relationship patterns among stakeholders, and it gives a strong foundation in the agent-based model needed in contemporary freight transportation modeling.

En este trabajo se explorará la relación que establece el tiempo verbal, en su significación semántica y pragmática, con la interpretación de dos de las perí-frasis modales del español mexicano: haber de y tener que. Se considerarán únicamente los tiempos simples y se dejará de lado el futuro por tener una naturaleza teórica conflictiva. Se plantea que el tiempo verbal interviene en la interpretación de la modalidad (deóntica o epistémica) y que el mecanismo a través del cual se logra esta intervención es una implicatura escalar que explota tanto el principio Q propuesto por Horn, así como la implicatura R que pro-pone el mismo autor.

Democracia e educação em direitos humanos no Brasil
Authors: Mota Helena de Assis
Published: September 2020

O presente artigo aborda a Educação em Direitos Humanos – EDH e seu desenvolvimento na esfera educacional brasileira. Proposta formalmente no Brasil pelo PNEDH - Plano Nacional de Educação em Direitos Humanos, a EDH é incompatível com a plataforma política da extrema-direita em ascensão nacional e internacionalmente. No ambiente escolar também pode ser considerada problemática por modelos de gestão não-participativos e produtivistas, já que promove o questionamento explícito de pilares como hierarquia, democracia e liberdade dentre os educandos, além de não figurar entre as matérias tradicionalmente exigidas nas avaliações educacionais. Destaca-se deste estudo que a defesa da perspectiva de gestão democrática alinhada aos fundamentos de direitos humanos presentes nos programas de pós-graduação das universidades públicas nacionais indica serem estes espaços privilegiados de reflexão sobre as iniciativas voltadas para a disseminação da EDH para gestores educacionais e educadores em geral, a fim de capilarizar suas temáticas e auxiliar concretamente a implementação do PNEDH sem descuidar da perspectiva humanista intrínseca à proposta.

LO SPIRITO MANIFESTATORE, NELLA PNEUMATOLOGIA DI PAVEL N. EVDOKIMOV
Authors: Putti Alberta Maria
Published: September 2020

L’uomo nuovo, l’uomo pneumatico, è al centro della riflessione teologica di Pavel N. Evdokimov (1901-1970). Argomenta che l’azione dello Spirito Santo non tanto è comprensibile con una analisi esclusivamente og­gettiva dell’agire di Dio in relazione all’uomo. Egli ritiene si tratti di riconoscere l’importanza dell’accoglienza dei doni dello Spirito dentro un duplice movimento: l’uomo vive prima una fase di conversione, e di lotta, a cui segue un movimento di ascesi che scaturisce dall’aver accolto i doni dello Spirito Santo. Santificandoci, lo Spirito Santo trasmette “qualcosa” della sua propria natura perché noi si possa compiere la volontà del Padre. Lo Spirito Santo imprime nell’uomo il suo Soffio vitale e, senza confusione, si fa co-soggetto della nostra vita in Cristo. L’uomo che è stato risoffiato dal Figlio del suo stesso Spirito, diventa immagine di Cristo nel mondo; respira del suo stesso soffio, della sua stessa vita.
SPACE ANGELS: ANGELOLOGY IN C. S. COSMIC LEWIS’S TRILOGY
Authors: Caldas Carlos
Published: September 2020

The Northern Irish author C. S. Lewis (1898-1963) was one of the outstanding Christian thinkers of the last century. A prolific author, he moved through different areas, such as literary criticism, youth literature, science fiction, and texts of theological exposition and of apologetics. In science fiction there is his remarkable “Cosmic Trilogy”: Beyond the Silent Planet, Perelandra, and That Hid­eous Strength. In these three books, Lewis presents a vast array of themes. Among these is angelology,the systematic study of heavenly beings known as angels. The aim of this article is to present the major influences that Lewis used to build his angelology: old Jewish literature, exemplified in texts such as the Ethiopian Enoch (or the Book of Enoch or First Enoch), and the biblical tradition itself. The article will seek also to defend the hypothesis that, using fiction, Lewis builds an imaginative and suggestive theology that is a critique of the rationalism of continental theol­ogy of his day.
A HERMENEUTICS OF IGNATIAN MYSTIQUE: CREATION IN CHRIST
Authors: Salles Walter Ferreira
Published: September 2020

It has become commonplace among scholars of Ignatian mysticism to establish a dialogue between the theme of creation and modern or postmodern ecological sensitivity in order to update the practice of the Spiritual Exercises of St. Ignatius of Loyola. The trajectory of this essay leads the reader through some aspects of the debate that this attempt to update has raised. The dual objective of this reflection is to show that the theme of creation in Ignatian mystique is in­separable from the idea of creation in Christ, and that the neglect of Christology structuring Ignatian mystic of Spiritual Exercises often leads to practices that no longer deserve the adjective of Christian neither Ignatian. This article is a descrip­tive and interpretative investigation based on a bibliographic study that is divided into four parts: the specification of the terms hermeneutic and mystical, the context of the Spiritual Exercises’ text, its elaboration, and finally the contemplation of the life of Christ as Creator.

Published: September 2020

This paper deals with the determination of the radiation quality correction factor (kQ) well-type ionization chamber for the measurement of Co-60 brachytherapy. The measurement of the brachytherapy source has been done in the hospital brachytherapy facilities. The measurement of air Kerma has been done using three different ionization chambers 0.6 cm3, 30 cm3, 80 cm3, which have calibration factor traceability for Co-60 and one well-type ionization chamber which calibrated for Ir-192. The determination of the radiation quality correction factor (kQ) was determined based on the results of the air Kerma ratio between measurements using ionization chambers, which have traceability to Co-60 and Ir-192 sources. The results of the measurement of the reference air Kerma rate (RAKR) obtained from the three chambers were 21.36, 19.87, 19.34 mGy.m2.h-1, while the results of measurements with ionization chambers get a value of 19.01 mGy.m2.h-1. The kQCal results from 0.6 cm3 ionization chamber get a value of 1.07. The kQCal value was compared with the value of Andreas Schuller’s et al. kQreff of 1.05 and get a deviation of 2.2%. Implementation of the booth kQ value on the results of the RAKR from the HDR1000Plus well-type ionization chamber in the measurement of brachytherapy in two different facilities gets maximal deviation 1.7% with dose value from Treatment Planning System (TPS). The deviation was in the acceptable range of ±5%. Based on this, the use of radiation quality correction factor (kQ) value can be implemented as one method if it does not have the traceability factor calibration of the Co-60 brachytherapy source.

Published: September 2020

Water is an essential need for humans and consumed as drinking water after fulfilling the health requirement in the Republic of Indonesia Minister of Health Regulation No.492/Menkes/Per/IV/2010. Due to the increasing demand, there are currently many refilled drinking water stores as an economical and practical alternative way to people. However, their safety still needs to be tested in the laboratory. This condition is impractical so that it needs a portable measuring instrument especially based on the TDS sensor that can measure the total dissolved solids (TDS) and electrical conductivity (EC) at once, which determines the taste and safety of the water. TDS sensor calibration at  80.5 to 966 ppm shows a 93.4% accuracy; 99.8% precision and 1.3 ppm hysteresis. In comparison, EC calibration at 161 to 1932 microsiemens/cm produces an average of 82.3% accuracy, 97.1% precision, and 1.0 microsiemens/cm hysteresis.

Este trabalho apresenta a modelagem e análise dos efeitos da corrosão por carbonatação em elementos de concreto armado através de um modelo numérico baseado no Método dos Elementos Finitos. A fim de controlar e minimizar os danos associados à corrosão faz-se necessário deter ferramentas e conhecimento suficientes para entender os efeitos desta manifestação patológica sobre o comportamento mecânico do concreto armado. Diante dos resultados obtidos, constatou-se que a depender do nível de corrosão das armaduras, o elemento de concreto tem seu estado de tensão e deformação comprometido. Ademais, os resultados apontam a eficiência do modelo desenvolvido e a sua aplicabilidade frente à simulação do comportamento mecânico de estruturas de concreto armado sujeitas à corrosão uniforme.

Published: September 2020

Este trabajo muestra un modelo analítico para el diseño de zapatas combinadas de esquina sometidas a una carga axial y dos momentos flexionantes ortogonales por cada columna. El modelo toma en cuenta la presión real del suelo debajo de la zapata, y la metodología se basa en el principio de que la integración de la fuerza de corte es el momento. El diseño actual considera la presión máxima en todos los puntos de contacto. Este modelo se verifica por equilibrio de fuerzas de corte y momentos. La aplicación del modelo se presenta por medio de un ejemplo numérico. Por lo tanto, el modelo propuesto es el más apropiado, ya que genera un mejor control de calidad en los recursos utilizados.

Case:

We present the rare event of median nerve bony entrapment after a supracondylar distal humerus fracture in a child. The median nerve was both clinically and electrically still, partially intact at 2 years after the injury. The nerve was surgically extracted from the bone. Follow-up evaluation a year later showed motor and sensory improvement. We found only 2 similar reports in the literature and one similar postmortem example.

Conclusion:

We hope that this case brings awareness of an unusual complication after a commonly encountered injury.

Iron toxicity affects the growth and yield of rice plant. Overcoming the damage of rice production by iron toxicity requires furthermore researches from laboratory to field levels. Here, we study responses of rice genotypes to iron toxicity between vegetative stage in hydroponic and whole grow stages in the pot. The first experiment was hydroponic experiment using twelve rice genotypes which were growth in the Yoshida Solution with addition of 0.2 % of agar. Three level of iron was given at 0, 500 and 700 ppm. The second experiment was the pot experiment using alluvial soil added with 3.000 ppm of ferrous combine with four levels of potassium and the control on Cilamaya Muncul (tolerant), Inpara 8 (moderate tolerant) and IR 64 (susceptible). In hydroponic experiment, even though the symptom appeared obviously, the leaf bronzing score (LBS) of tolerant and sensitive genotypes were not different. Physiological traits were significantly affected by Fe treatment in all varieties. Then symptom and physiological traits were significantly correlated. Through the pot experiment, it was confirmed the tolerance of each varieties. However, we couldn’t see the correlation between the LBS on hydroponic and soil at this time. And the heading delay was new finding, but it depended on varieties. We also could see the possibility of potassium application to inhibit iron toxicity but still we need to explore how it works.

O termo de consentimento livre e esclarecido (TCLE) refere-se ao documento responsável por esclarecer ao paciente o seu diagnóstico, as modalidades de tratamento disponíveis, o prognóstico e os eventuais riscos passíveis de ocorrência em detrimento da realização de um determinado tratamento. Deve ser instituído em todas as especialidades clínicas, principalmente para casos complexos, uma vez que nestas situações busca-se manter dentes com prognósticos duvidosos na cavidade bucal. Uma situação desafiadora na Endodontia compreende o tratamento de dentes necróticos com ápices incompletamente formados. Por anos, estes casos foram tratados por meio das técnicas de apicificação, todavia, por não permitirem o desenvolvimento da raiz em espessura e comprimento, apresentavam considerável índice de fratura radicular. Diante dessas limitações, uma modalidade contemporânea de tratamento foi proposta, a Endodontia Regenerativa (ER), capaz de permitir o término do desenvolvimento radicular e fechamento apical, com resultados mais promissores. Por tratar-se de um tratamento relativamente recente, a elaboração de um termo de consentimento livre e esclarecido para estas situações clínicas faz-se necessária, com vistas a resguardar o profissional e o paciente. Assim, o presente trabalho teve como objetivos revisar a literatura quanto à importância da elaboração de um TCLE para pacientes tratados por meio da técnica de ER, bem como sugerir um modelo de documento. É relevante que o Cirurgião-dentista elabore e aplique o TCLE para pacientes que serão submetidos à ER, devendo incluir neste documento todas as informações referentes ao tratamento, para que em casos de questionamentos ético-judiciais, o mesmo o auxilie na comprovação da adequada conduta profissional
Effect of Temperature and Alcohol on the Determination of Critical Micelle Concentration of Non- Ionic Surfactants in Magnetic Water
Authors: Al-Hatem Aamer A.
Published: September 2020

The determination of critical micelle concentration of selected non-ionic surfactants (Tween 20,40 and 80) have been investigated using magnetic water(MW)as an aqueous medium.Conductometry technique is used to determine critical micelle concentration.The effect of alcohol addition and temperature variation at the range(293.15 -303.15K) are also pursued. It is concluded that the process of micellization is spontaneous and endothermic because of the observed free energy of micellization (ΔGom) , enthalpy change of micellization  (ΔHom), and entropy change of micellization (ΔSom) for the system was also studied.The properties of the non-ionic surfactants were studied, both in absence and presence of alcohol. The results obtained were explained in light of hydrophobic-hydrophilic interactions and chain length of alcohol.The temperature change has slight effect on the micellization process. .

New Versions of Liu-type Estimator in Weighted and non-weighted Mixed Regression Model
Authors: Alheety Mustafa Ismaeel Naif
Published: September 2020

This paper considers and proposes new estimators that depend on the sample and on prior information in the case that they either are equally or are not equally important in the model. The prior information is described as linear stochastic restrictions. We study the properties and the performances of these estimators compared to other common estimators using the mean squared error as a criterion for the goodness of fit. A numerical example and a simulation study are proposed to explain the performance of the estimators.

Published: September 2020

In this paper, the Azzallini’s method used to find a weighted distribution derived from the standard Pareto distribution of type I (SPDTI) by inserting the shape parameter (θ) resulting from the above method to cover the period (0, 1] which was neglected by the standard distribution. Thus, the proposed distribution is a modification to the Pareto distribution of the first type, where the probability of the random variable lies within the period  The properties of the modified weighted Pareto distribution of the type I (MWPDTI) as the probability density function ,cumulative distribution function, Reliability function , Moment and  the hazard function are found. The behaviour of probability density function for MWPDTI distribution by representing the values of    This means, the probability density function of this distribution treats the period (0,1] which is ignore in SPDTI.
