A Geoid Slope Validation Survey (2017) in the rugged terrain of Colorado, USA

The orchid flora of Myanmar is highly diverse but as yet poorly known in the continental Asia, which is largely a result of periods of past instability and political isolation of the country. Also the remoteness of many orchid-rich areas and the difficulties of investigation in rugged terrain have also played a role (Ormerod & Kumar, 2003; Kurzweil & Lwin, 2014). According to recent estimates about 800 orchid species are distributed in Myanmar (Kurzweil & Lwin, 2014), which were probably underestimated. Many new distribution records and new species have been published in the last few years (Ormerod, 2002, 2006, 2012; Ormerod & Kumar, 2003, 2008; Ormerod & Wood, 2010; Nyunt, 2006; Kurzweil et al., 2010; Kurzweil & Lwin, 2012a,b; Tanaka et al. 2011).

Abstract Remote sensing and Geographical Information System (GIS) are the most effective tools in spatial data analysis. Natural resources like land, forest and water, these techniques have proved a valuable source of information generation as well as in the management and planning purposes. This study aims to suggest possible land and forest management strategies in Chakia tahsil based on land use and land cover analysis and the changing pattern observed during the last ten years. The population of Chakia tahsil is mainly rural in nature. The study has revealed that the northern part of the region, which offers for the settlement and all the agricultural practices constitutes nearly 23.48% and is a dead level plain, whereas the southern part, which constitute nearly 76.6% of the region is characterized by plateau and is covered with forest. The southern plateau rises abruptly from the northern alluvial plain with a number of escarpments. The contour line of 100 m mainly demarcates the boundary between plateau and plain. The plateau zone is deeply dissected and highly rugged terrain. The resultant topography comprises of a number of mesas and isolated hillocks showing elevation differences from 150 m to 385 m above mean sea level. Being rugged terrain in the southern part, nowadays human encroachment are taking place for more land for the cultivation. The changes were well observed in the land use and land cover in the study region. A large part of fallow land and open forest were converted into cultivated land.

To Come

Uneven action characterized Federal attacks all along the Union line. In James B. McPherson’s Seventeenth Corps, which held the center of Grant’s line, the only serious attack was conducted by Thomas E. Ransom’s brigade and it failed to come closely to grips with the entrenched Confederates on its sector. In John A. McClernand’s Thirteenth Corps, holding the left of the Union line, all that was done was to move the three divisions of the corps forward to reach positions from which they could launch a serious attack. This was all that seemed possible given the rugged terrain and heavy Confederate artillery fire. The Federals had not conducted a general attack or mounted a serious effort to find and break through weak points in the enemy defence line. Their enthusiasm had dampened somewhat but they still retained strong confidence in ultimate success. The effect of the Union repulse of May 19, however, was dramatic among the Confederates. It wiped away most of the demoralization caused by their defeats in Grant’s overland march and made them much more confident of holding Vicksburg until the Confederate government could mount an effort to relieve them from outside.

Posture Adjustment

This paper proposes a hexapod robot posture control method for rugged terrain to solve the problem of difficulty in realizing the posture control of a foot robot in rough terrain. The walking gait and original position of a six-legged robot is planned, and the Layer Identification of Tracking (LIT) strategy is developed to enable the robot to distinguish mild rugged terrain and severe rugged terrains automatically. The virtual suspension dynamic model is established. In mild rugged terrain, the posture maintenance strategy is adopted to keep the stability of the torso. In severe rugged terrain, the posture adjustment strategy is adopted to ensure the leg workspace and make it more widely adapt to the changing terrain, and a gravity center position adjustment method based on foot force distribution is designed to use foot force as feedback to control the position and attitude. The experiment of posture control in rough terrain and climbing experiment in the ladder terrain shows that the hexapod robot has good posture maintenance and posture adjustment effects when traversing complex terrain through the posture maintenance strategy and the posture adjustment strategy. Combined with the terrain identification method based on LIT, the hexapod robot can successfully climb the ladder terrain through the identification of the changing ladder terrain, and the movement of the posture adjustment process is stable.
