The SSI story What it is, and how it was stalled and eliminated in the International Standardization arena

SSI or Systems Software Interface is the name of a project once proposed by Japan to ISO/TC 97 (now ISO/IEC JTC 1) to standardize interfaces between application programs and various systems software, which are now commonly called application program interfaces (API), to accomplish portability of future applications. The proposal was not accepted as originally intended and ended up with a technical study conducted by ISO/IEC JTC 1 /TSG-1 (Interfaces for Application Portability), which has eventually triggered the recent international activity on OSE (Open System Environment). This article gives a background story of various efforts and reactions related to the SSI proposal, and tries to analyze why this apparently important proposal has failed. It also presents some issues to be considered in the present and future information technology standardization activities.

Observation System Experiments for Typhoon Nida (2004) Using the CNOP Method and DOTSTAR Data

This study investigated the influence of dropwindsonde observations on typhoon forecasts. The study also evaluated the feasibility of the conditional nonlinear optimal perturbation (CNOP) method as a basis for sensitivity analysis of such forecasts. This sensitivity analysis could furnish guidance in the selection of targeted observations. The study was performed by conducting observation system experiments (OSEs). This research used the fifth-generation Mesoscale Model (MM5), the Weather Research and Forecasting (WRF) model, and dropsonde observations of Typhoon Nida at 1200 UTC 17 May 2004. The dropsondes were collected under the operational Dropsonde Observations for Typhoon Surveillance near the Taiwan Region (DOTSTAR) program. In this research, five kinds of experiments were designed and conducted: (1) no observations were assimilated; (2) all observations were assimilated; (3) observations in the sensitive area revealed by the CNOP method were assimilated; (4) the same as in (3), but for the region revealed by the first singular vector (FSV) method; and (5) observations within a randomly selected area were assimilated. The OSEs showed that (1) the DOTSTAR data had a positive impact on the forecast of Nida's track; (2) dropsondes in the sensitive areas identified by the MM5 CNOP and FSV remained effective for improving the track forecast for Nida on the WRF platform; and (3) the greatest improvement in the track forecast resulted from the CNOP-based (third) simulation, which indicated that the CNOP method would be useful in decision making about dropsonde deployments.     

铁观音绿茶茶多酚提取工艺研究

将有机溶剂提取法这一技术应用于提取绿茶的有效成分---茶多酚.采用正交实验法优化茶多酚的最佳提取条件,选择浸提温度、浸提次数、浸取时间和有机溶剂的浓度作为考察因素,以茶多酚的提取率为评价指标,通过单因素试验的考察,每个因素选取4个水平.得出最佳的提取工艺为:温度65℃,洗提次数3次,有机溶剂提取时间35 min,有机溶剂浓度55%.在这种条件下从绿茶中提取的茶多酚的收率为最高.并采用红外波谱法对提取出的产品进行定性分析,检测得出绿茶提取物的主要成分为茶多酚.

Application Portability Profile (APP)—The US government's Open System Environment profile OSE/1 version 2.0

Federal information systems initially developed from isolated islands of computing. Through progressive changes, these individual systems became connected by common users and common information needs. These systems are now well on the way to migrating toward computing environments that consist of distributed, heterogeneous, networked applications, databases, and hardware. The concept of a Federal computing environment that is built on an infrastructure defined by open, consensus-based standards is well on its way to becoming a de facto means of organizing these systems. Such an infrastructure is called an Open System Environment (OSE).

An Open System Environment encompasses the functionality needed to provide interoperability, portability, and scalability of computerized applications across networks of heterogeneous, multi-vendor hardware/software/communications platforms. The OSE forms an extensible framework that allows services, interfaces, protocols, and supporting data formats to be defined in terms of nonproprietary specifications that evolve through open (public), consensus-based forums.

A selected suite of specifications that defines the interfaces, services, protocols, and data formats for a particular class or domain of applications is called a profile. The Application Portability Profile (APP) integrates industry.
