Comparative Study of Transmission Line Junction vs. Asynchronously Coupled Junction Diplexers

Author(s):  
Eugene A. Ogbodo

A conventional diplexer with a T-junction transmission line is designed in this work and compared with a new approach of designing a diplexer using the asynchronously coupled resonant junction (ACJ). The use of ACJ is to explore its features associated with enhancing the output response of the diplexer as well as its ease in control and implementation of the external couplings at the common port of an all-resonator-base diplexer. The measured and simulated responses of the diplexers were compared, and they agreed with each other.

The Common properties (community property) is an asset that the husband and wife acquired during the household lifes, which both of them is agree that after united through marriage bonds, that the property produced by one or both of them will be common property. It shows, that if there's an agreement between husband and wife before marriage (did not to unify their property), then the property produced both will not become a joint treasure. Thus, if a husband or wife dies, or divorces, then the property owned by both of them can be distributed in accordance with their respective shares, another case when the two couples are not making an agreement, then the property gained during marriage bonds can be divided into types of communal property. In Islamic law, this kind of treasure is not contained in the Qur'an or Sunnah. Nor in Islamic jurisprudence. However, Islamic law legalizes the existence of common property as long as it is applicable in a society and the benefit in the distribution of such property. In contrast to the positive law, this property types have been regulated and described in the Marriage Law, as well as the Islamic Law Compilations, which became the legal restriction in the affairs of marriage in force in Indonesia. In this study, the author tries to compile the existence of common property according to the Islamic law reviews and positive law.

This article presents three variants of the Pulse Width Modulation (PWM) for the Double Square Multiphase type Conventional Matrix Converters (DSM-CMC) supplying loads with the open-end winding. The first variant of PWM offers the ability to obtain zero value of the common-mode voltage at the load’s terminals and applies only six switches within the modulation period. The second proposal archives for less Total Harmonic Distortion (THD) of the generated load voltage. The third variant of modulation concerns maximizing the voltage transfer ratio, minimizing the number of switching, and the common-mode voltage cancellation. The discussed modulations are based on the concept of sinusoidal voltage quadrature signals, which can be an effective alternative to the classic space-vector approach. In the proposed approach, the geometrical arrangement of basic vectors needed to synthesize output voltages is built from the less number of vectors, which is equal to the number of the matrix converter’s terminals. The PWM duty cycle computation is performed using only a second-order determinant of the voltages coordinate matrix without using trigonometric functions. A new approach to the PWM duty cycles computing and the load voltage synthesis by 5 × 5 and 12 × 12 topologies has been verified using the PSIM simulation software.

This paper presents a comparative study of two Indo-Portuguese creoles, Korlai Creole Portuguese (KP) and Daman Creole Portuguese (DP). Using recently collected data, the phonology, pronominal systems, TMA markers, syntactic properties, and lexical items of KP and DP are compared and contrasted. The question of the common vs. independent origin of KP and DP is also discussed.

The first part of the article shows that in the mid-1960s some Soviet researchers of the European integration problems concluded that integration did not correspond to the Leninist-Stalinist theory of the general crisis of capitalism. On the contrary, it corresponded to some Western concepts of the custom union, the common market, and economic integration. A new approach to the European integration studies was offered by the Institute of World Economy and International Relation (IMEMO), established in 1956. For many decades IMEMO was serving as the focal point for the European integration studies, and was providing the Soviet leadership with analytical information. The number of inquiries from authorities increased significantly. Firstly, it can be explained by the achievements of integration. Secondly, it was due to the growth of economic cooperation between the USSR and the EEC. Thirdly, Moscow defined new foreign policy priorities towards Western countries including Europe. There were two turning-points of bilateral relations: with France – in 1966, and with Germany – in 1969. The Organization for security and cooperation in Europe (OSCE) was established during final session of the top-level Conference of European States in Helsinki in August 1975. Fourthly, experience of the EEC was relevant for the COMECON
