Analysis of the mean squared derivative cost function

In this paper, we investigate the mean squared derivative cost functions that arise in various applications such as in motor control, biometrics and optimal transport theory. We provide qualitative properties, explicit analytical formulas and computational algorithms for the cost functions. We also perform numerical simulations to illustrate the analytical results. In addition, as a by-product of our analysis, we obtain an explicit formula for the inverse of a Wronskian matrix that is of independent interest in linear algebra and differential equations theory.Comment: 28 page

The F@ Framework of Designing Awareness Mechanisms in Instant Messaging

This paper presents our research on awareness support in Instant Messaging (IM). The paper starts with a brief overview of empirical study of IM, using an online survey and face-to-face interviews to identify user needs for awareness support. The study identified a need for supporting four aspects of awareness, awareness of multiple concurrent conversations, conversational awareness, presence awareness of a group conversation, and visibility of moment-to-moment listeners and viewers. Based on the empirical study and existing research on awareness, we have developed the F@ (read as fat) framework of awareness. F@ comprises of the abstract level and the concrete level. The former includes an in-depth description of various awareness aspects in IM, whilst the latter utilises temporal logic to formalise fundamental time-related awareness aspects. F@ helps developers gain a better understanding of awareness and thereby design usable mechanisms to support awareness. Applying F@, we have designed several mechanisms to support various aspect of awareness in IM

Chogyal\u27s Sikkim: Tax, Land & Clan Politics

During the Chogyal (Tib. chos rgyal1) reign, the first and last monarchy in Sikkim, land and various forms of taxes derived from land ownership were powerful instruments of the ruling class, namely the Chogyal family, the aristocratic clans, and the royal lamas. It is the objective of this paper to examine the institution of land ownership and taxation as a reflection of the deeply seated and potent clan politics of Sikkim. Through available records and literature as well as interviews with head lamas, monastic affiliates and the Sikkimese public, using a combination of narratives and analysis, this author hopes to present a balanced, yet personal treatment of the subject. The research took place in West Sikkim, of which monasteries and heritage sites stood witness to the birth and development of the Chogyal government, making it an ideal location for this historical inquiry
