Multi-resolution modeling(MRM) is required when simulating objects in variable resolution and can be applied for interoperating systems, which simulate objects in fixed resolution. However, most interoperation middleware do not support MRM, so participating models must handle several issues to simulate MRM system. In this paper, we propose an interoperation system, which is composed of several different resolution models, based on the High Level Architecture and Run-Time Infrastructure(HLA/RTI). In the proposed architecture, each model participates to a HLA federation through MRM adapter application, which supports data resolution conversion and HLA services while communicating with the model. MRM adapter application can be implemented based on an MRM adapter, and an adapter application development tool is proposed to support developing the application. Using the tool, developers can easily implement data resolution conversion component plugged-in HLA adapter. A case study is implemented in the proposed MRM system, and shows that models of different resolution works successfully with dynamic resolution changes.

This paper proposes design and implementation for Seamless Handoff method between adapters in a system environment where both wired and wireless adapters are present First of all, by settingLayer 2 address of wired adapter to Layer 2address of wireless adapter, then generate virtual adapter on the above layer to make these two adapters operate on an IP address. Under the condition, when wired communication via the wired adapter gets disconnected while in service, wireless handoff occurs by mapping information on the wireless adapter to the virtual adapter. According to the method proposed in this paper, continuous session can be obtained even when handoff between wired and wireless adapters occurs at lower level in an application where both IP address and Port address are used to maintain session since If address does not change.

The topology of LLC half bridge resonant converter provides ZVS characteristic. The voltage stress and current stress are smaller than that of the general resonant converters. So the LLC HB resonant converter can be considered as a optimal circuit for the notebook computer adapter. In the adapter design, we should consider the weight, the size and the overheat of the adapter. Thus the higher efficiency is an essential particular. First of all, the optimal design of transformer is the most important facts. Some parameters should be considered in order to get the highest efficiency. The adapter is designed through the considering of these parameters including the PFC circuit as the pre-regulator. It converts AC line input into about DC 390V link voltage of the LLC HB converter input and the converter has 16V/90W ratings. The efficiency measured is about up to 93%.

최근 거대 언어모델의 등장과 동시에, 많은 매개변수를 효과적으로 학습하는 방법인 효율적인 매개변수 미세조정(Parameter Efficient Fine-Tuning) 연구가 활발히 진행되고 있다. 이 중에서 Adapter는 사전학습 언어모델(Pretrained Language Models)에 몇 개의 추가 병목 구조 모듈을 삽입하여 이를 학습하는 방식으로, 등장한 이후 다양한 연구 영역에서 주목받고 있다. 그러나 몇몇 연구에서는 병목 차원을 증가시켜 미세 조정보다 더 나은 성능을 얻는다는 주장이 나오면서, 원래의 의도와는 다른 방향으로 발전하고 있다는 의견도 있다. 이러한 맥락에서, 본 연구에서는 기존의 Adapter 구조를 개선한 MAdapter를 제안한다. MAdapter는 본래 Adapter에 중간 층을 추가하되 학습 가능한 매개변수의 수는 오히려 줄이는 방법으로, 전체 매개변수 수 대비 1% 내외 만을 학습에 활용하며, Adapter 대비 절반 정도의 매개변수만을 사용하여 기존 결과와 비슷하거나 더 나은 성능을 얻을 수 있는 것을 확인할 수 있다. 또한, 병목차원 크기 비교와 중간 층 개수 분석을 통한 최적의 MAdapter 구조를 찾고, 이로써 효율적인 매개변수 미세조정 방법을 제시한다.

In this study, The details for a seismic adapter designed to easily connect concrete structures and reinforcement materials for the in-plane reinforcement of aged structures were proposed. Proposed seismic adapter was tested for performance using a dynamic simulation on a 2-story column-beam structure, scaled to half of the real size. The experimental results showed that the reinforced test specimens using the seismic adapter improved their energy dissipation capacity by 3.5 times compared to the non-reinforced specimens. It was confirmed that the seismic adapter experienced no damage within its general usage range, thus proving its effectiveness. Subsequently, upon loading until the limit of deformation (a deformation angle of 3.3%), it was observed that one of the M10 bolts connecting the adapter and the reinforcement at the lower part of the first floor broke. Considering this finding, when applying seismic retrofitting in real situations, emphasis should be placed on the design of the bolts and anchors connecting the seismic adapter. This aspect warrants further research for validation.

When rotating the clutch drum in the power take-off (PTO) gear box of an armored recovery vehicle, lots of inner oil is drained through the adapter by centrifugal force. Therefore, a lack of lubrication is caused by inner oil loss, and the bearing is damaged by overheating. This study, therefore, aims to design an oil-controlling adapter by using shape alteration to prevent oil loss. Both the original and improved adapters were tested at 1,800rpm by using an operational test machine. When applying the original adapter to the gear box, the bearing was damaged by overheating, which was caused by the lack of lubrication. When applying the improved oil-controlling adapter, on the other hand, it prevented the loss of inner oil. Applying the improved adapter is expected to prevent the overheating caused by lack of lubrication.

In this paper, we describe the design of the ATM adapter circuit in the BSC for IMT-2000 Network. This ATM adapter circuit can convert received ATM cell into TDM data in the BSC and vice versa. In the ATM adapter, we implemented both AAL1 and AAL5 functions to provide constant bit rate voice data and variable bit rate packet data servives, simultaneously.

Recently, it is increased to use the portable device with small size. It is also increasing for demand of a small size adapter. To reduce the size of components, switching frequency has to be increased. But it causes higher switching loss and temperature of components. Especially, the temperature of adapter must be limited because adapter can be easily touched when portable device is being charged. To reduce temperature of adapter, high efficiency is essential. To solve this problem, this paper proposes design of resonance frequency optimization for LLC converter with high efficiency and low temperature of passive components.

A previous adapter have a single-ouput, however, a demand of a multi-output adapter increase in the recent industrial site. In order to satisfy the demand, in this research, we implement a programmable high efficiency multi-output adapter. The basic structure of the adapter introduced in this paper is a sort of flyback. The way for producing the reference voltage of the adapter proposed is similar to the way in the general flyback implemented with TL431. In addition to the basic concept of the design, however, we introduce a digital variable resistor, AD5246BKSZ10-RL7 and a microcontroller for changing a programmable multi-output. It makes output be variable that the digital variable resistor change the reference voltage of the adapter by order of the microcontroller. The adapter output voltage is controllable in the range of 20V by the user, and the power efficiency is proven to be 85%.

초고속 통신망에 근간이 되는 ATM 통신망에 SUN W/S, PC 컴퓨터들을 접속시키는 ATM Adapter Card은 하드웨어, 시스템 소프트웨어 및 응용 소프트웨어로 구성된다. 하드웨어의 구조 및 시스템 소프트웨어의 구조, 성능에 따라서 ATM Adapter Card 위에서 수행되는 응용 소프트웨어의 성능을 결정할 것이다. ATM Adapter Card는 효율적으로 Native ATM 응용 소프트웨어를 지원할 뿐 아니라, 기존의 TCP/IP 응용 소프트웨어를 수용하는 IPoverATM, LAN Emulation 기능도 지원하여야 한다. 또한 PVC(Permanent Virtual Channel), SVC(Siganlling Virtual Channel)을 위하여 ATM Forum UNI 3.1에 준한 Signalling도 필요하다. 이러한 조건들을 만족시키기위하여, 현재 개발 완료된 SUN W/S SBus용 디바이스 드라이버는 DLPI(Data Link Provider Interface), STREAM 방식으로 구현하였으며, 현재 개발 중인 PC PCI용 ATM Adapter Card의 디바이스 드라이버는 NDIS 3.0 방식으로 구현 다양한 Transport Layer를 ATM망에 수용하도록 하였다. Signalling은 Daemon Process를 이용하여 구현하였다.
