Unknown Objects

As there come to be more applications of intelligent robots, their task object is becoming more varied. However, it is still a challenge for a robot to handle unfamiliar objects. We review the recent work on the feature sensing and robotic grasping of objects with uncertain information. In particular, we focus on how the robot perceives the features of an object, so as to reduce the uncertainty of objects, and how the robot completes object grasping through the learning-based approach when the traditional approach fails. The uncertain information is classified into geometric information and physical information. Based on the type of uncertain information, the object is further classified into three categories, which are geometric-uncertain objects, physical-uncertain objects, and unknown objects. Furthermore, the approaches to the feature sensing and robotic grasping of these objects are presented based on the varied characteristics of each type of object. Finally, we summarize the reviewed approaches for uncertain objects and provide some interesting issues to be more investigated in the future. It is found that the object’s features, such as material and compactness, are difficult to be sensed, and the object grasping approach based on learning networks plays a more important role when the unknown degree of the task object increases.

Recent Policy

This article critically analyses the opportunities for Australia to revitalise its strategically important manufacturing sector in the wake of the COVID-19 pandemic. It considers Australia’s industry policy options on the basis of both advances in the theory of industrial policy and recent policy proposals in the Australian context. It draws on recent work from The Australia Institute’s Centre for Future Work examining the prospects for Australian manufacturing renewal in a post-COVID-19 economy, together with other recent work in political economy, economic geography and labour process theory critically evaluating the Fourth Industrial Revolution (i4.0) and its implications for the Australian economy. The aim of the article is to contribute to and further develop the debate about the future of government intervention in manufacturing and industry policy in Australia. Crucially, the argument links the future development of Australian manufacturing with a focus on renewable energy. JEL Codes: L50; L52; L78; O10; O13: O25; O44; P18; Q42

Unknown Objects

This paper focuses on the perception step of robotic grasping unknown objects in order to get a stable grasping hypothesis. At first, hierarchical shape context feature is proposed to depict the local and global shape character of a sample point along the edges of the object. Moreover a kind of random forests classifier is adopted to recognize the grasping candidates in the image from vision system so that a 2D grasping rectangle can be generated through kernel density estimation. Finally, by means of stereo matching, the grasping rectangle can be mapped into the 3D space. Thus, the center of the grasping rectangle can be applied as the center of the gripper. The approaching vector and the grasping rectangle direction can be employed to determine the pose of the gripper. Simulated experiments showed that a reasonable and stable grasping rectangle can be generated for various unknown objects.

This article considers the traditional approach to the ’state’ Models of corporate governance, namely shareholder Model and stakeholder Model. It then considers the extent to which developments in a recent accession EU country, Poland, reflects either of these Models or adopts a hybrid approach. It then offers proposals for the future development of corporate governance within Poland.

Source Of Information

Evidential markers encode the source of information that an individual (the evidential Origo) has for a proposition. In root declaratives, the Origo is always the speaker (see Korotkova 2016 and references therein). Instead, questions often display interrogative flip: the Origo shifts to the hearer (Garrett 2001; Speas & Tenny 2003, a.o.). While interrogative flip is widely attested across languages, some evidentials have been reported not to flip in questions (see, e.g., San Roque, Floyd & Norcliffe 2017; Bhadra 2017). What determines whether evidentials flip or not? Recent work (Korotkova 2016; Bhadra 2017) has proposed that there is a correlation between lack of flip and bias in questions. This paper contributes to our understanding of the interaction of evidentials and bias by investigating the behaviour of questions with the Italian non-predictive future. We characterize the non-predictive future as an inferential evidential marker (see also Mari 2009; Eckardt & Beltrama forthcoming), and show that lack of flip for the future correlates only with a particular type of bias: a reversal of the default bias associated with negative polar questions (Frana & Rawlins forthcoming). We trace back this pattern to an interaction between the evidential component of the future and the operator that triggers bias reversal.

Scholarly Attention

To fight the risks caused by excessive self-disclosure especially regarding sensitive data such as genetic ones, it might be desirable to prevent certain disclosures. When doing so, regulators traditionally compel protection, for example by prohibiting the collection and/or use of genetic data even if citizens would like to share these data. This chapter provides an introduction into an alternative approach which has recently received increased scholarly attention: privacy protection by the use of nudges. Such nudges may in the future provide an alternative to compelled protection of genetic data or complement the traditional approach. This chapter first describes behavioral psychology's findings that citizens sometimes act irrational. This statement is consequently explained with the insights that these irrationalities are often predictable. Thus, a solution might be to correct them by the use of nudges.

The Future

Vehicular clouds is an active area of research that has emerged at the nexus of conventional cloud computing and vehicular networks. The defining differences between conventional and vehicular clouds include the heterogeneity and volatility of compute resources and the bandwidth-challenged network fabric. A variety of new architectures and services for vehicular clouds have been proposed, mostly as incremental extensions of the VANET platform. As vehicular cloud research continues and expands, a careful eye should be kept on the restrictions that come with the mobility, limited network, and heterogeneity of resources. The first main contribution of this chapter is to survey recent work of VCs with an eye on the realistic and unrealistic. Our second main goal is to realign the VC community with a realistic vision for the future by spelling out a number of challenges faced by the VC research community.

Single Method

The traditional approach to forecasting involves choosing the forecasting method judged most appropriate of the available methods and applying it to some specific situations. The choice of a method depends upon the characteristics of the series and the type of application. The rationale behind such an approach is the notion that a “best” method exists and can be identified. Further that the “best” method for the past will continue to be the best for the future. An alternative to the traditional approach is to aggregate information from different forecasting methods by aggregating forecasts. This eliminates the problem of having to select a single method and rely exclusively on its forecasts.

Social Profiles

Speculation concerning the future direction of linguistic evolution, despite its obvious pitfalls, has a long tradition, not to mention attraction, in linguistics. In the French domain, one need only think of Pulgram (1967) or of various works by Ashby concerning « Future French » (1974, 1977), both of whom reflect on ideas present in French scholarship dating from the early decades of this century (e.g. Meillet, 1921, 1936; Vendryes, 1923). Recent work in typology, showing apparently orderly progression from one language state to another, has buttressed speculative efforts, as have many of the results of sociolinguistics, where clear trends in age or social profiles often allow one to infer directionality and even end result on the basis of ongoing change.
