A new approach on designing l1 optimal regulator with minimum order for SISO linear systems

For a SISO linear discrete-time system with a specified input signal, a novel method to realize optimal l1 regulation control is presented. Utilizing the technique of converting a polynomial equation to its corresponding matrix equation, a linear programming problem to get an optimal l1 norm of the system output error map is developed which includes the first term and the last term of the map sequence in the objective function and the right vector of its constraint matrix equation, respectively. The adjustability for the width of the constraint matrix makes the trade-off between the order of the optimal regulator and the value of the minimum objective norm become possible, especially for achieving the optimal regulator with minimum order. By norm scaling rules for the constraint matrix equation, the optimal solution can be scaled directly or be obtained by solving a linear programming problem with l\ norm objective.     

Making XML document markup international

In name and in practice, the World‐Wide Web (hereafter Web) is used around the World beyond English‐speaking areas. This creates a tremendous need to internationalize standard terminology used in the technologies that make the Web possible. Existing efforts on XML internationalization (i18n) and localization (i10n) have focused on the content of XML documents instead of the terms used in markup (annotations) such as elements and attributes. The SGML standard ISO 8879 supports the use of Unicode (ISO 10646) throughout a document, including markups. However, most elements and attributes of XML documents are still defined in English, thereby limiting their use among non‐English speakers. This paper presents an XSLT‐based method that can completely localize the markup of XML documents into different natural languages. We also describe how the proposed technique can be applied to translation problems in programming (e.g. C and Java) or documentation (e.g. LAT<sub>E</sub>X or other formatting languages) so that a program or a document can be converted to and from an XML format.

Analog Circuit Design Methodology in a Low Power RISC Microprocessor

There are various kinds of analog CMOS circuits in microprocessors. IOs, clock distribution circuits including PLL, memories are the main analog circuits. The circuit techniques to achieve low power dissipation combined with high performance in newest prototype chip in the Super H RISC engines are described. A TLB delay can be decreased by using a CAM with a differential amplifier to generate the match signal. The accelerator circuit also helps to speed up the TLB circuit, enabling single-cycle operation. A fabricated 96-mm<sup>2</sup> test chip with the super H architecture using 0.35-<img src="/content/lj178v60651l867g/xxlarge956.gif" alt="mgr" align="MIDDLE" BORDER="0">m four metal CMOS technology is capable of 167-MHz operation at 300 Dhrystone MIPS with 2.0-W power dissipation.

Margules (Journal of Comparative & Physiological Psychology, 1970[Oct], Vol 73[1], 1-12; see record 1971-03588-001). On page 3, paragraph 1 of the Method section, the angle of implantation of cannulas was 6° from the perpendicular; in paragraph 2 of the Method section, the following sentence was omitted: All rats were maintained on a reversed dark-light cycle (lights off at 0800 hr. and on at 2000 hr. EST) and were drugged in the dark. On page 10, paragraph 6, line 10 of the Discussion section, "abolishes" should read "enhances."

Theoretical consistency test of steam transport properties

The kinetic theory of polyatomic gases is used to test the mutual consistency of the thermal conductivity, viscosity and specific heat of low-pressure steam from 100° to 700°C. No inconsistency exists within the cited tolerances of the skeleton tables recommended by the Sixth International Conference on the Properties of Steam, but there is some basis for suspecting that the high-temperature thermal conductivity values are slightly low. Methods for tightening the consistency bounds are suggested.

太白大曲以大麦、豌豆为原料。采用中高温发酵而成。按培曲品温控制及大曲特性可分为青茬曲、红心曲和槐瓤曲。不同品种的太白大曲其糖化力、液化力、发酵力和生香能力各不相同。经试验证明。太白大曲科学搭配、合理使用是提高太白酒产质量的重要技术措施。按青茬曲30％、红心曲30％和槐瓤曲40％组成混合曲,传统工艺操作,搭配使用,其出酒率和优质品率分别比单一大曲提高0．77％～2．40％和8．92％～13．80％。     

Classification Using Φ-Machines and Constructive Function Approximation

This article presents a new classification algorithm, called CLEF, which induces a <img src="/content/r2l063ugu635327g/xxlarge934.gif" alt="PHgr" align="BASELINE" BORDER="0">-machine by constructing its own features based on the training data. The features can be viewed as defining subsets of the instance space, and they allow CLEF to create useful non-linear functions over the input variables. The algorithm is guaranteed to find a classifier that separates the training instances, if such a separation is possible. We compare CLEF empirically to several other classification algorithms, including a well-known decision tree inducer, an artificial neural network inducer, and a support vector machine inducer. Our results show that the CLEF-induced <img src="/content/r2l063ugu635327g/xxlarge934.gif" alt="PHgr" align="BASELINE" BORDER="0">-machines and support vector machines have similar accuracy on the suite tested, and that both are significantly more accurate than the other classifiers produced. We argue that the classifiers produced by CLEF are easy to interpret, and hence may be preferred over support vector machines in certain circumstances.     

Normal forms in BL and ŁΠ algebras of functions

Three types of normal forms are introduced for fuzzy logic functions: disjunctive, conjunctive and additive. Disjunctive and conjunctive normal forms are considered in two variants: infinite and finite. It is proved that infinite normal forms are universal representation formulas whereas finite normal forms are universal approximation formulas for any <i>L</i>-valued function where <i>L</i> is a support set of any complete BL-algebra. The additive normal form <img src="/content/bu6pu4l11fr5670j/xxlargeldquo.gif" alt="ldquo" align="MIDDLE" BORDER="0">lies<img src="/content/bu6pu4l11fr5670j/xxlargerdquo.gif" alt="rdquo" align="MIDDLE" BORDER="0"> in the middle of the two others. For all of them the estimation of the quality of approximation is suggested.     

Caste-dependent reactions to soldier defensive secretion and chiral alarm/recruitment pheromone inNasutitermes princeps

The soldier frontal gland secretion of<i>Nasutitermes princeps</i> induces strong short-range caste-specific alarm and attraction in both soldiers and workers. Soldiers are excited and patrol the surroundings of the source. The secretion per se does not induce ejection of additional secretion. Large workers of the second stage or older are massively attracted when tested in homogeneous groups. They focus their activities much more accurately than the soldiers around the source. The workers' reaction is less intense in the presence of soldiers. Large and small workers of stage 1 scarcely react at all to the secretion, whether tested in homogeneous or mixed groups. These results suggest the following complementary roles of soldiers and workers in defense. The first line of defense is provided by soldiers, which immobilize and incapacitate mobile enemies with their sticky secretion. Defense then is completed by older large workers as they eliminate the source of disturbance. The absence of reaction of young workers, small or large, confirms previous reports on age polyethism in<i>Nasutitermes</i> observed in other contexts: young workers tend to stay in the nest. Alarm reactions are elicited by a source of (+)-<i><img src="/content/q4j9525251l018xh/xxlarge945.gif" alt="agr" align="BASELINE" BORDER="0"></i>-pinene, the major monoterpene in the secretion, while its enantiomer, almost absent from the secretion, induces a much weaker reaction.
