Investigating multi cyclic gas (N2 and CO2) huff and puff have been conducted by long sandpack simulations with four different crude oils from Jiangsu oilfield. According to the production differential pressure and the production regularity during huff and puff, the production process was divided into three sections; the first one is free gas production section; the second section is low viscou...

Thanks to Dr Hillsman for his comments. The basic forced expiratory technique maneuversdescribed initiallybyThompsonand Thompson1 and later by Pryor et al2 did not include instruction to whisper “huff.” I agree that modifications to techniques previously established from a research base might add or detract from their efficacy. In retrospect, the readers might have been better served had I dist...

This paper revisits a model for elliptic curves over Q introduced by Huff in 1948 to study a diophantine problem. Huff’s model readily extends over fields of odd characteristic. Every elliptic curve over such a field and containing a copy of Z/4Z× Z/2Z is birationally equivalent to a Huff curve over the original field. This paper extends and generalizes Huff’s model. It presents fast explicit f...

This paper presents the Tate pairing computation on generalized Huff curves proposed by Wu and Feng in [22]. In fact, we extend the results of the Tate pairing computation on the standard Huff elliptic curves done previously by Joye, Tibouchi and Vergnaud in [14]. We show that the addition step of the Miller loop can be performed in 1M+(k+15)m+2c and the doubling one in 1M+1S+(k+12)m+5s+2c on t...

Only one healthy volunteer reported feeling no nasal discomfort while inhaling dry oxygen; all the other subjects reported some degree of discomfort and irritation. These data clearly demonstrate that humidification of oxygen reduces nasal discomfort that can occur in both young healthy volunteers and older patients with pulmonary disease, particularly at flows 3 L/min. Two limitations of this ...

Recently two kinds of Huff curves were introduced as elliptic curves models and their arithmetic was studied. It was also shown that they are suitable for cryptographic use such as Montgomery curves or Koblitz curves (in Weierstrass form) and Edwards curves. In this work, we introduce the new generalized Huff curves ax(y − c) = by(x−d) with abcd(ac−bd) 6= 0, which contains the generalized Huff’...

Abstract: The oil recovery factor from shale oil remains low, about 5 to 7% of the oil in place. How to increase oil recovery from shale oil reservoirs is attracting more and more attention. CO2 huff-and-puff was historically considered one of the best approaches to improve the oil rate. Most previous simulation studies have been based on dual porosity, but simulation results from dual-porosity...

Huff curves are well known for efficient arithmetics to their group law. In this paper, we propose two deterministic encodings from Fq to generalized Huff curves. When q ≡ 3 (mod 4), the first deterministic encoding based on Skalpa’s equality saves three field squarings and five multiplications compared with birational equivalence composed with Ulas’ encoding. It costs three multiplications les...

We show that for the Hardy class of functions H 1 with domain the ball or polydisc in CN , a certain type of uniform convexity property (the uniform Kadec-Klee-Huff property) holds with respect to the topology of pointwise convergence on the interior; which coincides with both the topology of uniform convergence on compacta and the weak ∗ topology on bounded subsets of H 1. Also, we show that i...
