This paper proposes new method for object reference which enables a person to find surrounding objects and develops a navigation system named CoCo. CoCo employs an ultrasonic directional speaker with a rotating base. Ultrasonic wave transmitted by an ultrasonic directional speaker is converted to audible sound when it reflects on floor, wall, or object. Based on this property, CoCo can emit aud...

In the commercial production of roses, introducing a method to reduce the time of propagation with maximum success is crucial. This study was conducted to investigate the effect of different concentrations (0, 1500, 3000, 4500 mg/L) of Indole-3-butyric acid (IBA) on propagation of three cultivars of Rosa hybrid L. ('Dolce Vita', 'Samurai' and 'Utopia') by stenting (simultaneous cutting and graf...

an experiment was conducted to evaluate the effects of different levels of mineral and vitamin premix on performance and egg traits of laying hens from 37 to 49 weeks of age. two hundred and forty laying hens (hy-line w-36 strain) were randomly assigned to 5 dietary treatments of four replicates each with 12 hens per replicate). the levels of mineral and vitamin premixes in the experiment were ...

In this paper, we analyze the effect of the conversion price of CoCo bonds on equity holders’ incentives. First, we use an option-pricing context to show that CoCo bonds can magnify equity holders’ incentives to increase the riskiness of assets and decrease incentives to raise new equity in a crisis in cases in which conversion transfers wealth from CoCo bond holders to equity holders. Second, ...

In this paper, we propose CoCo, a novel framework for establishing covert timing channels. The CoCo covert channel modulates the covert message in the inter-packet delays of the network flows, while a coding algorithm is used to ensure the robustness of the covert message to different perturbations. The CoCo covert channel is adjustable: by adjusting certain parameters one can trade off differe...

Effects of Fe and Trichoderma harzianum Bi strain on plant growth and development of Spathiphyllum were investigated. Experiments were carried out in an glasshouse and in pots filled with soil, perlite and coco peat (1:1:1) were used as the growing medium. Plant roots (seedlings with three leaves) were inoculated with Trichoderma (0 and 8% w/w) as media mixture. Fe spray (0, 0.75, 1.5, 3 g/L), ...

in order to evaluate the effect of foliar application of salicylic acid on the qualitative characters of strawberry fruit, a factorial experiment (treatment+ the time of harvesting) based on completely randomized design with 3 replications was conducted in a greenhouse and the laboratories of department of horticultural science of university college of agriculture and natural resources, univers...

INTRODUCTION Premix insulin analogs are a well-established treatment for type 2 diabetes (T2D). However, there is a lack of simple, clear guidance on some aspects of their use. These include choosing a regimen for insulin initiation, recognizing when patients need intensification of therapy, and switching from basal-bolus to a premix insulin analog when appropriate. METHODS An independent exp...
