Abstract:

Abstract. A theorem is presented describing a transformation by means of which it is possible to assign to an elementary multiport with fairly general constitutive equations (including all kinds of controlled sources, nullors, ideal transformers, etc.) a modified multiport with the same all-pole terminal behavior. The branch set of this modified multiport is augmented with so called auxiliary branches whereas its constitutive equations are always in conductance form. Therefore an interconnection of a family of multiports transformed in this manner can always be analyzed by means of a system of

Abstract:

Valves are essential components of a fluid management system, and their proper functioning is critical to ensuring the system's efficiency and durability. Multiport ball valves are versatile and commonly used in various industries to control fluid flows. These valves have multiple ports or outlets, allowing for different flow paths and configurations. One of the key considerations when using multiport ball valves is the flow characteristics within the valve itself. The flow within multiport ball valves is governed by several factors, including the design of the valve and the pressure drop acro

Abstract:

In this paper, a simulation analysis of a multiport DC/DC converter with Boost topology has been carried out. The converter topology consists of two inputs and one output. This analysis aims to obtain the first version to cope with partial shading in a PV system using a multiport converter. The analysis shows the multiport converter's functionality to track the maximum power point of the two PV panels using the Perturb and Observe (P&O) algorithm in normal irradiance conditions and partial shading situations. A switching time of the switches was established to perform individual power extr

In this paper, a robust current control of the hybrid renewable energy system (HRES), based on the PV-Wind system, is proposed. The HRES is connected to a multiport converter to synchronize the multi-source system with one DC-Bus. Due to their ability to integrate many renewable energy sources (RES) individually or simultaneously, multiport converters (MPC) are an innovative method suitable for renewable energy applications. Recently, many DC-DC converter designs and topologies have emerged to ensure the highest possible efficiency of hybrid RESs. The multiport converter is a typical coupling

Maximizing solar energy harvesting and miniaturizing DC-to-DC converters will be a difficult task for the CubeSat that operates in low earth orbit (LEO), where size and weight are limited.

A novel and compact scalable antenna system is designed for multiport applications. The basic design is built on a square patch with an electrical size of0.82λ0×0.82λ0(at 2.4 GHz) on a dielectric substrate.

The 4-port antenna can be simply rearranged to 8-port and 12-port systems.

When a short-circuit fault occurs on one bus, the energy storage can maintain uninterrupted power supply to the remaining healthy bus.

Abstract:

In response to the increasing demand for voice, data, and multimedia applications, the next generation of wireless communication systems is projected to provide faster data rates and better service quality to customers. Techniques such as Multiple-Input–Multiple-Output (MIMO) and diversity are being studied and implemented to meet the needs of next-generation wireless communication systems. Embedding multiple antennas into the same antenna system is seen as a promising solution, which can improve both the system’s channel capacity and the communication link’s quality. However, for small handhe

Abstract:

This paper introduces a novel multiport power converter with modular architecture for photovoltaic (PV)-battery based power systems. Compared to conventional centralized multiport converters, the proposed converter significantly improves the utilization of PV available energy and battery capacity as it does not require a high number of series-connected PV and battery modules. The proposed converter also eliminates the need for additional battery cell/module equalizer circuitry by being able to implement directly energy management strategies that consider the different capabilities of battery m

Abstract:

Background. Prostate cancer (PCa) is a malignant tumour that forms from the glandular epithelium of the prostate gland. Today, prostate cancer is one of the most frequently diagnosed cancers in the male population. The method of choice for radical treatment of localised prostate cancer is robot-assisted prostatectomy (RAPP). Purpose. To evaluate the modern possibilities of robotic surgery and to determine the relevance of transition from multiport to single-port system. Conclusion. Elevated BMI is a predisposing factor for urinary incontinence and erectile dysfunction (ED) in the postoperative

Abstract:

An analysis of multirecess hydrostatic bearings with linear flow-pressure supply characteristics is presented. These characteristics can be obtained using either a constant supply pressure source with a laminar flow restrictor before each recess, or, as suggested in this paper, a multiport viscous pump. Analysis of the viscous pump-bearing system is made for odd numbers of recesses, and it is shown that a staggered or skip-one sequence of connection of the pump ports to the bearing recesses gives the least unbalanced reaction between the pump rotor/stator. The flow-pressure characteristics of

Abstract:

A data path consists of memory elements (i.e. registers), data operators (i.e. ALUs) and interconnection units (i.e. buses) to control the data transfers in the digital system. Many approaches to memory synthesis have been proposed in the literature. However, only single port memory is considered for register allocation and no efficient synthesis approach for multiport memory synthesis. In this paper, an efficient method, Partitioned Dependence Matrix (PDM), is presented for memory synthesis which deals not only with single port memory synthesis but also multiport memory synthesis according to
