“…This material was used as a phantom heart, breast or prostate tissue in earlier works [14][15]. The grasper was programmed to grasp the sample with a 1 sec ramp loading, 5 sec hold, and a 1 sec unloading [16], and with 1 minute interval to recover [17]. The grasping angle and the grasping force were characterized (Fig.…”

Feedback from sensory modalities is crucial for the precise grasping of tissues during minimally invasive robotic surgery. The aims of the study are to determine the influence of visual and haptic feedback on the detection of threshold forces and to evaluate the applicability of the sensory integration model to a surgical grasping task. A sensorized surgical grasper and a fingertip haptic force feedback device were used. Three types of stimuli were presented (i.e. visual-alone, haptic-alone, and bimodal visual and haptic stimuli). Threshold forces of 100 mN and 87.5 mN were detected for visual and haptic feedback, respectively. When bimodal feedback was provided, the participants detected a threshold force of 75 mN. The threshold force for the bimodal condition was 28.6% lower than the visual-alone feedback and 15.4% lower than the haptic-alone feedback stimuli. Our bimodal condition results showed that there was a 13.1% difference between the experimental result and the predicted value from the sensory integration model. The threshold force discrimination was strongly influenced by the haptic force feedback. It is likely that the tissue stiffness can be more intuitively perceived through the direct force stimulation of the fingertip than just by visual observation alone. Cues like small deformations or changes in the grasping angles of the surgical tool are more difficult to interpret visually as compared to the haptic modality.

“…Finite Element Analysis has been an effective tool for analyzing contact interactions between artificial fingers and various objects [6], [7], [8], [9], [10], [11], [12]. For this data set, the index finger of the low-cost 3D printed prosthetic hand was subjected to numerical failure analysis using LS-DYNA software (mmps R8.1.1, Livermore Software Technology Corporation (LSTC), USA) [13].…”

In this article, three different data sets are presented to evaluate a representative of openly accessible 3D printed prosthetic hand. The first data set includes grasping force measurements of human hand and low-cost 3D printed hand. Three grasping functions were evaluated, spherical, cylindrical, and precision grasps. The experimental test was performed using a wearable tactile sensor. The second data set includes the numerical analysis of prosthetic fingers made from Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA) materials under different carrying loads. The numerical analyses were carried out by LS-DYNA software. The files can be used for the prosthetic fingers’ evaluation and for the selection of suitable material. The third data set includes the experimental tensile test of ABS and PLA materials. The mechanical properties were calculated from the results, which can be used in the design and fabrication of products from these materials. All the datasets are available from Harvard Dataverse: https://doi.org/10.7910/DVN/GCPAIL.

“…Procurement is a key factor in attaining client satisfaction and project success (Rwelamila, 2010). International Conference of Socio-economic Researchers ICSR (2016) in Cabibihan et al, (2016) affirmed that procurement as "an organizational system that assigns specific responsibilities and authorities to people and organizations, and specifies how different elements of a construction project would relate". There are various construction procurement methods which hail from the need to develop strategies that will meet the clients need in different circumstances (Oyeranti et al, 2011).…”

This study investigated the effectiveness of procurement of construction materials among road workers in Ekiti State. The descriptive research design was used for this study. Sixty copies of structured instrument were developed to collect information from the road construction workers. The data were analyzed using Statistical Package for the Social Science. The research questions were answered using percentage and mean while the hypothesis was analyzed using analysis of variance and tested at 0.05 level of significance. The finding of the study revealed that there is upward increase in the cost of procuring construction materials by workers in Ekiti, several factors such as sequence of materials delivery, availability of material in the local market, material changes in type, and specification during construction among others affect the procurement of construction materials by road workers in Ekiti State. It was revealed that majority of the road construction workers are experienced. It was also revealed that the experience of road construction workers does not influence the factors affecting the procurement of construction materials by workers in Ekiti State. It was recommended among others that concerted efforts should be made by construction industries on ways of procuring construction materials at a cheaper rate to avoid increase in the cost of construction in the State. It was also recommended that there is need to appoint and register procurement experts to manage various procurement of construction materials so that the cost of procurement of materials will be reduced and better attitudes toward the procurement of construction materials should be encouraged among the construction workers.
