Breeding cycle in rubber extends to 20-30 years between pollination and yield assessment, distributed over three selection stages. Five hectares of small scale trial of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.], was established in the Northwestern region of São Paulo State, Brazil. The population comprises 98 clones mostly derived from intensively selected plus tree in the natural forest of rubber tree in the Amazon. Three open pollinated progeny tests were established in three experimental stations. Seedlings from 98 progenies including a commercial check (CC) wer

Summary In 1978 a 10 ha clonal seed orchard of black pine (Pinus nigra Arnold) was established in the area of Koumani in the western part of Peleponnesos, Greece. The orchard comprises 52 clones derived from intensively selected plus trees in the natural forest of black pine of Peloponnesos. In 1991 three open pollinated progeny tests were established in Peloponnesos, proximal to the villages of Raches, Vlachokerasia and Vamvakou. Seedlings from 52 families including a commercial check (CC) were planted in each one of the three locations. Assessments were made when the trees were 4, 7 and 9 ye

A complete cycle of within-family selection for 2nd-year height in jack pine (Pinusbanksiana Lamb.) was accomplished. The expected absolute gain from a theoretical population is 9.3%. The expected gain calculated using actual selected parental group means was 6.5% for upper selection and −6.5% for lower selection; realized gains were 5.1% for upper selection and −3.7% for lower selection. Reasons for reductions in the realized gain compared with expected gain include (i) a finite base population size; (ii) biological constraints such as inconsistent seed production; (iii) non-normal distributi

Vineyard peach native population in our country represents important and rich source of genetic variability. Establishment of the genetic gain and differences concerning genetic variability are very important in selection of the genotypes with different usability. In according to the start up population and after selection of 25% intensity important properties such as fruit quality indexes were examined. Those were fruit weight, output, appearance, taste, aroma, soluble solid and total sugar content and titratable acidity. Besides variability components, coefficient of variation and heritabili

AbstractRealized gains for coastal Douglas-fir (Pseudotsuga menziesii var. menziesii) were evaluated using data collected from 15-year-old trees from five field trials planted in large block plots in the northern Oregon Cascades. Three populations with different genetic levels (elite - high predicted gain; intermediate - moderate predicted gain; and unimproved - wild seedlot) were compared at two planting spacings (1.8 × 1.8 m and 3.6 × 3.6 m). The realized gains at age 15 averaged over both the elite and intermediate progeny were 17.2% for stand volume per hectare, 3.5% for mean height, and 4

This paper simulated different scenarios of breeding program for indigenous chicken and compared the selection response with realized genetic gain after one generation of selection. A one stage discrete generation deterministic simulation approach using SelAction program was used. Two genetic parameters were employed. The phenotypic variances and heritability used were 25,000g and 0.25, 3040 and 0.51, respectively. For each case, 300 hens and

AbstractIn the context of sustainable product development, Life Cycle Assessment (LCA) methods are used to gain knowledge about environmental hotspots and derive options for improvement. In light of international efforts to promote sustainable development, Social LCA (SLCA) is an emerging method to assess potential socio-economic impacts of products and services. Even when available data is limited in the early stages of materials, process, and product development, the implementation of SLCA benefits target-oriented research and development to support sustainable development.

Obesity is known to cause physical and metabolic diseases. It is often assumed by people (including the healthcare workers) that the person with obesity lacks self-control in matters of diet and physical exercise, and is therefore responsible for his or her weight. Persons with obesity have to face sarcasm, barbs, and discrimination due to their condition. They often have difficulty in getting jobs or have to accept lower than standard pay for their work. Although weight gain requires calorie intake in excess of calorie expenditure, it is sometimes not easy for the person to restrict calories

Conflict of interest (COI) can be defined as a set of circumstances that creates a risk that professional judgment or actions regarding a primary interest (e.g., a patient’s best interests) will be unduly influenced by a secondary interest (e.g., financial or professional gain for the counselor). Although conscious and intended unethical behavior resulting from a COI, most COIs occur at a subconscious level and are a normal aspect of human psychology and behavior. It can be very difficult for any professional to recognize a COI, and even more difficult for highly ethical people to realize that

Proportional Integral Derivative (PID) is the most popular controller that is commonly used in wide industrial applications due to its simplicity to realize and performance characteristics. This technique can be successfully applied to control the behavior of single-input single-output (SISO) systems. Extending the using of PID controller for complex dynamical systems has attracted the attention of control engineers. In the last decade, hybrid control strategies are developed by researchers using conventional PID controllers with other controller techniques such as Linear Quadratic Regulator (

A new collaborative control strategy between time varying design parameters in LPV plants and the feedback controllers is proposed in the present paper. As the feedback control law the gain scheduling control scheme is adopted to guarantee the closed-loop L2 gain performance against the variation of the time varying parameter in the control object. The gain-scheduling controller can be obtained in an analytical manner by solving LMIs. For the closed-loop system with the LPV plant and the gain scheduling controller Genetic algorithm (GA), known as a so-called intelligent optimization method, is

The control of hydraulic valve-cylinder drives is still an active subject of research, and various linear and particularly nonlinear approaches has been proposed, especially in the last two-three decades. In many cases the proposed controllers appear to produce excellent tracking ability due to robust- and/or adaptive functionalities, but also often rely on full state feedback and/or cumbersome and elaborate parameter designs. Also, such sophisticated control approaches often lack tuning methods which, together with the lack of proven reliability, is likely to be the reason why such approaches

Gait-based person re-identification (Re-ID) is valuable for safety-critical applications, and using only 3D skeleton data to extract discriminative gait features for person Re-ID is an emerging open topic. Existing methods either adopt hand-crafted features or learn gait features by traditional supervised learning paradigms. Unlike previous methods, we for the first time propose a generic gait encoding approach that can utilize unlabeled skeleton data to learn gait representations in a self-supervised manner. Specifically, we first propose to introduce self-supervision by learning to reconstru

Abstract A task motion trajectory usually needs to be determined for the training process and mechanism design for rehabilitation patients since they are not capable of providing a normal motion. In this paper, a machine-learning-based approach of gait trajectory prediction for lower limb rehab patients is proposed to provide the basis for the design of simple 1-degree-of-freedom (DOF) rehab mechanisms. First, a large amount of gait trajectories from various healthy volunteers are collected along with their body parameters, and a normalization method is presented to trim/expand these trajector
