The stability of holonomic mobile manipulator can be improved effectively based on the stability twist constraint (STC). However, nonholonomic mobile manipulators are much more popular. In this paper, the stability of a nonholonomic mobile manipulator is improved with STC consideration. However, the constraint of nonholonomic mobility will affect the orientation of mobile base. Numerical simula...

This paper describes the ITNLP system participated in the Short Text Conversation (STC Chinese subtask) of the NTCIR12. We employed a Logistic Regression Model combined with pattern-based matching features to solve the STC problem. Deep learning methods were also tried in our experiment. Out of the 44 submitted runs our best performance run ITNLP-C-R3 ranked 8(Mean nDCG@1),12(Mean P+) and 9(Mea...

In bestimmten Migrationsprojekten existiert die Notwendigkeit für einen Wechsel der Programmiersprache. Dazu werden sogenannte Translatoren eingesetzt. Translatoren konvertieren in Analogie zu einem Compiler ein Programm einer Quellprogrammiersprache in ein Programm einer Zielprogrammiersprache. Der folgende Beitrag diskutiert die erweiterten Anforderungen an Translatoren gegenüber klassischen ...

Stanniocalcin-1 (STC-1) is made by kidney collecting duct cells for autocrine and paracrine targeting of nephron cell mitochondria. Here, the ligand stimulates respiratory uncoupling and calcium uniport activity. However, the underlying purpose of these actions and how the renal gene is regulated are poorly understood. In a previous study, we described the time-dependent, stimulatory effects of...

Short Text Conversation (STC) is a typical scenario in manmachine conversation, which simplifies the conversation into one round interaction and makes the related tasks more practical. This paper presents a simple approach to the Chinese STC task issued by NTCIR-12. Given a repository of post-comment pairs, for any query, we define three types of similarity and merged them according to empirica...

Dynamic coupling is an inherent behavior of the space robot system, which seriously affects motion accuracy system. This article focuses on how to guarantee base attitude stability semifloating robots, from a control perspective—namely, decoupling control. The quaternion representation system dynamics derived avoid singularity Euler angles. In consideration complicated and limited computing abi...

Absorption and storage of [14C]beta-carotene in control and beta-carotene-fed (BC-fed) rats were determined. Pre-feeding with beta-carotene for 2 weeks caused a 1.9-fold stimulation of its own absorption as well as its conversion to retinyl esters, whereas the absorption of [3H]retinyl acetate was unaffected. The liver and the lungs accounted for 60% and 30%, respectively, of the total recovere...

The design of space-time codes for wireless communications with relays is investigated by considering a pragmatic approach based on the concatenation of convolutional codes and BPSK/QPSK modulation to obtain cooperative codes. We propose a design criterion which aims at optimizing both diversity and coding gain, based on an asymptotic bound for frame error probability. This framework is useful ...
