In realistic environments, fully specifying a task model such that a robot can perform a task in all situations is impractical. In this work, we present Incremental Task Modification via Corrective Demonstrations (ITMCD), a novel algorithm that allows a robot to update a learned model by making use of corrective demonstrations from an end-user in its environment. We propose three different type...

This paper describes a new material, polyurethane-cement composite (PUC), used to strengthen a 29-year-old reinforced T-beam bridge in Harbin, China. Polyurethane-cement composite (PUC) is mixed with polyurethane raw material and cement. This technique is completed by pouring Polyurethane-cement composite (PUC) into the template. Ultimate bearing capacity of the bridge after reinforcement was d...

INTRODUCTION Bleeding to death is one of the leading causes of death speaking about violent death in general. Bleeding to death mostly happens through hurt organs or blood vessels of thorax, abdomen and neck or because of destruction of extremities or the whole body. Bleeding to death is very often the consequence of blood pouring, rarely of simultaneous pouring and suffusing of blood, and it i...

To reduce the volume of drinks and the risk of overconsumption, health professionals recommend the use of tall skinny instead of short wide glasses. Yet the results of the present study contradict this health advice. Participants who generously filled up a glass with lemonade served 9% more in tall narrow compared with short wide glasses (p<0.05). In addition, when pouring a small amount (i.e.,...

This article takes a single-tower cable-stayed bridge with steel-UHPC composite deck steel box girder as the research object and develops different casting plans for UHPC layer on deck. It analyzes influence of factors such block sequence deck, whether or not to set up post-casting section, counterweights range it additional deformation stress formed during construction stage, exploring impact ...

One of the methods used to surface hardening ductile iron is chilled cast iron. Chill as fast cooling rate in mold during solidification and chill thickness greatly affects hardness layer. The main material iron, SS 304. Casting uses sand casting method. Before pouring, plate has been inserted onto pattern that formed mold, then preheated at 700°C. Pouring was carried out a melting temperature ...

Real-time monitoring is crucial to assess hazards and mitigate risks of sustained volcanic eruptions that last hours months or more. Sustained have been shown produce a low frequency (infrasonic) form jet noise. We analyze the lava fountaining at fissure 8 during 2018 Lower East Rift Zone eruption Kīlauea volcano, Hawaii, connect changes in fountain properties with recorded infrasound signals f...

Affected by faults, fractures, and high ground stress, the deep shaft wall is prone to deformation fracture, which affects safety of mine construction. To investigate stress at horsehead gate connection, force-measuring bolt vibrating string concrete strain gauges were installed for on-site monitoring prior pouring. It was found that strains forces on divided into four stages during tedious The...

In this study, we proposed an advanced control system for tilting-ladle-type automatic pouring machines in the casting industry. Automatic have been introduced recently to improve working environment of process. conventional study on control, it has confirmed that flow rate contributes improving accuracy entire machine, such as outflow liquid’s falling position from ladle, weight filled mold, a...

Experiments were carried out against the red palm weevil, Rhynchophorus ferrugineus (Oliv.) (RPW in a private orchard containing varieties of Samani (domestic) and Ikhlas (imported) infested with weevil (RPW) El-Marg area, Cairo Governorate, Egypt, using Petroleum oil, Jojoba Inorganic salts, singly mixed each insecticides (Acetamiprid, Profenofos, Dimethoate) by injection spraying trunks, as w...
