SIS is a Satellite controller Integrated with Star sensors, which has been developed as a prototype model of a compact, low-cost satellite controller. SIS integrates attitude sensors into a star sensor and integrates several electronics for star identification, attitude determination, attitude control, and data handling into a single processing unit. SIS meets high reliability requirements by a...

The slow intelligence system (SIS) technology is a novel technology for the design of a complex information system that is aware of the environment through multiple sensors and capable of improving its performance over time. In this paper we describe a practical slow intelligence system test bed where super-components can be specified to describe interactions among components. These supercompon...

We describe the properties of guided modes in metallic parallel plate structures with subwavelength corrugation on the surfaces of both conductors, which we refer to as spoof-insulator-spoof (SIS) waveguides, in close analogy to metal-insulator-metal (MIM) waveguides in plasmonics. A dispersion relation for SIS waveguides is derived, and the modes are shown to arise from the coupling of convent...

For the Global Positioning System (GPS), signal-in-space (SIS) performance is key to the positioning accuracy and the integrity. In practice, SIS anomalies occasionally happens and the consequent user range errors of tens of meters or even more have been observed. In this paper, all potential SIS anomalies in the last decade are screened out by comparing the broadcast ephemerides/clocks with th...

BACKGROUND AND PURPOSE The purpose of this study was to examine proxy-patient agreement on the domains of the Stroke Impact Scale (SIS), as per the proxy-proxy perspective. METHODS Stroke patients were prospectively assessed by means of the NIH Stroke Scale, Barthel index, and modified Rankin scale. Proxies and patients answered the Hospital Anxiety and Depression Scale and the SIS 3.0. Compa...

Sustainability Indicators (SIs) have been popular among a section of the policy and science community for some years and are often promoted by this group as a potent vehicle to help make sustainable development a reality. One of the claimed strengths of SIs is their ability to present complex data and trends to policy makers. It is assumed that SIs can thereby help to make policy and indeed man...

Boulders from the Grūda Moraine, which is associated with the maximum extent of the Scandinavian Ice Sheet (SIS) during the last glaciation, and the Baltija (also referred to as the South Lithuanian), the Middle and North Lithuanian moraines, which are associated with recessional stages of the SIS, were sampled for surface exposure dating using Be. By combining these data with existing radiocar...

Objective: This study demonstrates that superior outcomes are possible when diabetic foot ulcers (DFU) are managed with tri-layer porcine small intestine submucosa (SIS). Approach: Patients with DFU from 11 centers participated in this prospective randomized controlled trial. Qualified subjects were randomized (1:1) to either SIS or standard care (SC) selected at the discretion of the Investiga...

The v-sis gene is able to transform cells by production of a growth factor that is structurally related to platelet-derived growth factor. This growth factor has been detected in the conditioned media of v-sis transformed cells, and is able to stimulate the autophosphorylation of the platelet-derived growth factor receptor. We have used the v-sis gene product to analyze the role of protein-enco...

Beside industrial product and solution business industrial services become increasingly important. The solution business for industrial plants poses challenges, which require the use of appropriate service information systems (SIS). In order to support the user actively during service execution the SIS developer needs to know these challenges to determine and prioritize the SIS requirements. If...
